Reifenhäuser Extrusion Lines Provide Carbon Footprint Calculation for More Sustainable and Economical Production

Reifenhäuser Extrusion Lines Provide Carbon Footprint Calculation for More Sustainable and Economical Production

Reifenhäuser is presenting a new digital solution for carbon footprint calculation at K 2022: the Carbon Footprint Dashboard. This enables film and nonwovens producers to see how the carbon footprint changes in ongoing production and identify how they can reduce their emissions. The dashboard thus contributes both to climate protection and to economic success, because a CO2 reduction is usually also accompanied by savings in energy and raw materials. The prerequisite for the carbon footprint calculation is the standard version of Reifenhäuser’s digital solution ExtrusionOS & c.Hub Middleware and the availability of the required data.

Dr. Tim Pohl, Director Sustainability and Business Development at the Reifenhäuser Group, explains: “The Carbon Footprint Dashboard shows the different emission sources over the production period. In the basic version, assumptions are made about the carbon footprint of the raw materials used and the calculation is based on the energy mix of Europe, for example. This is sufficient to determine initial potential for carbon footprint reduction. If more precise information is required, we can customize the calculation according to local conditions. Such a calculation becomes exciting when in-house recycled material is used.”

Carbon footprint calculation for manufacturing companies is quite complex and starts with the different methods of calculation – at the company level, but also at the product level. The corporate carbon footprint (CCF) balances the CO2 footprint for the entire company – from energy procurement to production to the vehicle fleet. The product carbon footprint (PCF) records all CO2 emissions that occur along the life cycle of a product, i.e. from raw materials to production and use to disposal.

Manufacturers of films and nonwovens can therefore approach the topic of calculation “bottom-down” via a corporate carbon footprint, or they can do it “bottom-up” via a product carbon footprint for each of their products. The latter is ideal if a broad product portfolio with different raw materials and recycled content is processed. For this purpose, a customer-specific carbon footprint dashboard can be created in Reifenhäuser’s ExtrusionOS software solution.

From an economic point of view, the carbon footprint calculation is worthwhile in any case: Producers can show the carbon footprint to third parties and thus certify a particularly sustainable product series, for example. This opens up new sales markets and increases economic success. In addition, the savings in energy and raw materials pay off, especially in view of the current high purchase prices.

Carbon footprint of a Reifenhäuser extruder
The Reifenhäuser Group has been following the path of the corporate carbon footprint for 10 years now. The machine manufacturer is energy certified according to ISO 50001 and reduces its emission sources every year. This year, for example, this includes the installation of a new photovoltaic system with which Reifenhäuser can produce more than 600,000 kWh of electricity and save approximately 175,000 kilograms of CO2 equivalents.

In addition, the PCF of components, such as screws and barrels, and of entire extruders was determined. One finding is that emissions during the production of the line components are significantly lower than emissions during the use phase. For example, the production of a 120 extruder generates a calculated one-time emission of around 27,000 kilograms of CO2 equivalents. In contrast, the operation of the extruder causes around 3.5 million kilograms of CO2 equivalents through electricity consumption over the course of ten years. In this case, the manufacturing process causes less than one percent of the PCF along the life cycle. By contrast, 99 percent is generated during the use of the extruder – so the leverage for reducing emissions is much greater at this stage. For extruder operators, investing in energy-efficient technologies and subsequent energy-saving measures is therefore doubly worthwhile – both the wallet and the environment benefit.

Reifenhäuser Provides Trade Fair Visitors at K 2022 With Fully Recyclable FFP2 Masks Free of Charge

Reifenhäuser Provides Trade Fair Visitors at K 2022 With Fully Recyclable FFP2 Masks Free of Charge

At K, the world’s largest plastics trade show, thousands of visitors come together to learn about the latest innovations – especially on sustainable plastics products. This year, visitors will already encounter one such innovation at the trade show entrance: fully recyclable and climate-friendly FFP2 masks. Reifenhäuser provides the masks for protection against respiratory infections to trade fair visitors free of charge at all entrances.

FFP2 masks have so far caused major problems when it comes to recycling: they are usually made of many different materials, for example functional layers of polypropylene and textile, nose clips made of metal, ear loops made of polyester. As a result, resources are lost to the circular economy, and the carbon footprint is devastating – especially due to the enormous increase in mask consumption caused by the Corona pandemic.

The mask for K 2022, on the other hand, consists of 99.7 percent polypropylene. It is therefore considered a mono-material product and is 100 percent recyclable. In concrete terms, this means that the nose clip is made of 100 percent polypropylene instead of wire. The same applies to the support layer, which is otherwise made of so-called Hot Air Cotton. The ear loops – usually made of PES (75 percent) and elastane (25 percent) – are 85 percent PP and 15 percent Cradle2Cradle certified elastane. The total elastane weight per mask is thus only 0.3 percent. The individual packaging for the FFP2 masks is also made of 100 percent PP and can be recycled together with the masks. The mask was produced by the Grabher Group, a specialist in technical textiles, using a Reifenhäuser meltblown line.

Reducing the carbon footprint
The sustainable FFP2 masks are not only fully recyclable, but also cause significantly less CO2 emissions during their production than conventional protective masks. The entire production process is designed to keep the carbon footprint as low as possible: the masks are manufactured entirely in the EU, avoiding long transport routes. CO2-neutral PP resins based on Borealis Bornewables, a renewable premium raw material that offers the same material performance as virgin polyolefin but is independent of fossil raw materials, are used for production. The nonwoven is produced with green power on energy-efficient Reifenhäuser line technology. Added up, a recyclable FFP2 mask thus has a CO2 footprint of only 8 grams of CO2 equivalents – that is one tenth of a conventional mask produced in Asia.

Reifenhäuser Blown Film Provides Technical Solution to One of the Biggest Challenges in the Processing of Recyclate

Reifenhäuser Blown Film Provides Technical Solution to One of the Biggest Challenges in the Processing of Recyclate

The line manufacturer Reifenhäuser Blown Film presents at K 2022 a technology that makes blown film producers independent of highly fluctuating recyclate qualities and ensures a stable production process – even when processing low-quality input material: EVO Fusion upgrades recyclate qualities.

With EVO Fusion, blown film producers also process previously unusable, lowest-quality recyclates into high-performance blown films for simple end-uses, such as trash bags or mailing bags. Until now, such low-grade recyclates could only be used for simple and thick-walled injection-molded products. In addition, producers can make higher-quality film from recyclates that could also be processed in the past.

Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains, “In order to drive the circular economy, recyclate rates in blown film products must increase and classic downcycling must be limited. With EVO Fusion, we offer a unique process that enables customers to process even low recyclate grades easily and economically into high-performance products and increase the recyclate content. In this way, processors open up new fields of application for recycled products.”

The EVO Fusion process relies on direct extrusion, which eliminates the need for energy- and cost-intensive regranulation of the raw material. This means that fluff (film shreds) and all types of production waste and PCR material can also be processed directly.

This is made possible by the twin-screw technology, which homogenizes the melt better and thus ensures a stable process. In addition, processors can degas the system very easily and effectively, removing unwanted components in the recyclate.

 

With EVO Fusion, even fluff (film snippets) and all kinds of production waste and PCR material can be directly processed into functional films for applications such as trash bags or mailing bags.

 

For processing better quality regranulates, Reifenhäuser recommends the EVO Ultra single-screw extruder. Thanks to optimized barrier as well as shear and mixing parts, this extruder processes recycled material as reliably and naturally as other raw materials – the ideal prerequisite for success in the growing market for products with a high recycled content.

Precise, Autonomous, Mechatronic: PAM Calibrates Coextrusion Adapters and Dies Automatically for Best Comfort, Quality and Productivity

Precise, Autonomous, Mechatronic: PAM Calibrates Coextrusion Adapters and Dies Automatically for Best Comfort, Quality and Productivity

At K 2022, Reifenhäuser is presenting its new PAM automation option for coextrusion adapters and slot dies in flat film and sheet production, and for extrusion coating for the first time worldwide. The high level of automation makes the machine operator’s work significantly easier, thus increasing line productivity and film quality. Energy consumption is also reduced, as manual adjustment bolts replace the conventional thermal expansion bolts.

Up to now, when starting up the extrusion line or changing products, many individual operations have been necessary until the coextrusion adapter and die are set correctly. Manufacturers lose time and money as a result. For this reason, Reifenhäuser has now developed an automation option that relieves line operators of this work: PAM (precise, autonomous, mechatronic).

With the PAM option, coextrusion adapter and die can be adjusted automatically and mechatronically – precisely controlled via the line’s operating panel. This is significantly faster than conventional control by hand or expansion bolt automation, and enables faster start-up of production, higher output and improved overall equipment efficiency (OEE). Scrap and material usage are significantly reduced. In addition, recipes that have been set once can be stored and recalled at any time. They can therefore be reproduced exactly – even by inexperienced line operators.

The stored setting parameters not only facilitate future production, but also the tracing of individual products and provide proof to customers. Another advantage of contactless calibration with PAM is that the line operator no longer has to work on the hot components, which increases work safety and prevents damage to the machine. PAM is optionally available for new Reifenhäuser “Pro” type coextrusion adapters and for various dies, but can also be retrofitted to existing lines regardless of the manufacturer.

PAM for coextrusion adapters
The Reifenhäuser coextrusion adaptor Pro is the only coextrusion system on the market that allows profiling of the individual layers while the line is running. Unlike conventional solutions, elements located in the adapter do not have to be removed, processed and reinstalled in a time-consuming process. Instead, profilers can be flexibly controlled individually or together during operation via a central adjustment.

“The PAM option goes one step further,” explains Hanna Dornebusch, application engineer at Reifenhäuser Cast Sheet Coating. “PAM automates the setting of the layer distribution and simplifies adjustments and optimizations through integrated recipe management. This is especially worthwhile for manufacturers of films with many layers and many product changes.”

While with simple 3-layer compounds the coextrusion adapter is adjusted in a few steps, up to 70 profilers have to be adjusted for barrier compounds with 11 layers, for example. Compared to manual adjustment by a machine operator, automation saves about half an hour of changeover time – depending on the number of profilers to be adjusted.

PAM for dies
From single actuators to translator technology, PAM is the logical innovation from decades of Reifenhäuser development in the field of die control. With two manual adjustment bolts, the system combines energy efficiency with low setup and operating complexity of the control system.

The PAM option is suitable for dies in flat film and sheet production as well as for extrusion coating. The system enables autonomous and mechatronic adjustment and control of the flex lip via the line control system. Depending on the die design, autonomous adjustment of the restriction bar, width adjustment and lip opening via adjustment of the lower die lip is also possible.

“With the PAM option, we now offer our customers a highly convenient solution with a fast return on investment,” explains Tim Bänsch, die product manager at Reifenhäuser Extrusion Systems. “Compared to dies that are adjusted with thermal expansion bolts, changeover time and energy consumption are significantly reduced.”

For example, a width changeover with PAM in a cast application with internal width adjustment is 78 percent faster than with a conventional system. In addition, PAM saves energy because no thermal expansion bolts need to be permanently powered. For example, switching from thermal expansion bolts to PAM for a 3,000-mm-wide die saves of about 130,500 kilowatt hours per year.

PAM is a joint development of the “Reifenhäuser Extrusion Systems” business unit, which specializes in extrusion components, and the “Reifenhäuser Cast Sheet Coating” business unit. The PAM option can be selected independently for coextrusion adapters and dies – but in combination, the automated components unleash their full strength.

 

With two manual adjustment bolts, PAM dies combine energy efficiency with low setup and operating complexity of the control system.

 

“We are one of the few machine builders in the market that manufacture everything ourselves – extruder, coextrusion adapter and die,” says Tim Bänsch. “Due to this hot part competence within the Reifenhäuser Group, we know the process technology interfaces very well and can design everything accordingly to each other – PAM takes it all to a new level.”

The K Was Sensational

The K Was Sensational

VDMA Plastics and Rubber Machinery Association draws positive balance of the world’s leading trade fair K in every respect

The plastics and rubber machinery manufacturers are drawing a very positive balance: K 2022 was the first international plastics trade fair to be held as a regular attendance event in the wake of the Covid pandemic. “It was very important for the industry to finally come together again. The relief at being able to meet and exchange ideas in person was palpable everywhere during the entire eight days of the fair,” said Ulrich Reifenhäuser, Chairman of the K Exhibitor Advisory Board and Chairman of the VDMA Plastics and Rubber Machinery Association. He added that exhibitors from the machinery and plant engineering sector had been able to present their technological innovations to a broad trade audience, and close multiple solid deals. “The event was a great success for everyone,” said Reifenhäuser.

K 2022 has given a huge boost to the circular economy for plastics. The interest of domestic and, above all, also foreign trade visitors exceeded the expectations of the mechanical engineering companies in a major way, which, in addition to their trade fair stands, presented their innovations specifically for the circular economy at the Circular Economy Forum of the VDMA. “With the Circular Economy Forum we have pointed the way and made a strong commitment to the circular economy. This was very well received by the visitors. The exhibitors themselves were a little surprised by the great interest on the part of the trade visitors,” said Thorsten Kühmann, Managing Director of the Plastics and Rubber Machinery Association within the VDMA on Wednesday at the close of K in Düsseldorf.

For eight days, at the forum, visitors were able to see on operational machines what is already technically feasible today as well as what will be possible in the future. The same applies to digitalisation solutions, whose important groundbreaker is OPC UA, the world language of production. The networked factory is more in demand than ever, because it is necessary to utilise transparency and control options in terms of energy reduction and resource efficiency. The technologies exhibited at K 2022 have demonstrated this potential in an impressive manner.

SABIC Demonstrates Its Expertise in the Building & Construction Market at K 2022 With Solutions for Enhanced Sustainability and Energy Efficiency

SABIC, a global leader in the chemical industry, invites visitors of the company’s booth D42 in Hall 6 during K 2022 in Düsseldorf, Germany (October 19–26) to experience a comprehensive portfolio of high-performance polymer solutions for the building & construction (B&C) industry. An increased global population and growing urbanization has created a dramatically rising demand for more sustainable, resource and energy efficient material solutions.

To meet these megatrends, SABIC has developed a number of specialized thermoplastic resin and sheet products that will be featured at the show with a focus on four B&C market segments – energy solutions, pipe solutions, structural glazing and solid sheet. Highlights in this exhibition area, include all of the B&C sheet products offered by the company’s Functional Forms business, which can be ‘walked through’ by means of a large-screen Explorer providing a virtual building environment that showcases various different applications in greater detail. For pipe solutions, SABIC’s new BiAx pipe technology will be on display. This technology offers substantial improvements over incumbent polyolefin pipes across the entire range of performance criteria.

The vast array of lightweight, robust and energy-efficient material and application samples on display includes:

Energy solutions
Renewable energy sources are vital for the world’s transition towards a carbon-free landscape, and solar energy can yield high results to make the change real. To further drive down energy consumption within buildings, solar roof panels are an effective solution but often hindered by the fact that many industrial roofs are not strong enough to carry glass photovoltaic panels. SABIC’s material solutions can make a difference in this field:

Floating photovoltaic panels: SABIC PP Compounds used in floaters for solar panels combine good UV resistance and recyclability for modular, stackable injection-molded floaters that are lightweight and easy to transport. Potentially they can be made by using post-consumer recycled PP and certified circular and renewable grades from SABIC’s Trucircle portfolio. Another solution is SABIC HDPE material, designed for blow molded floating modules offer long-term outdoor performance. Read more.

Lightweight photovoltaic panels: Solar panels made by Solarge using SABIC PP compounds show more than 50% weight reduction over incumbent glass-based competitors and can achieve a carbon footprint reduction of more than 25%. They can be used for both new and retrofitting installations on roofs that cannot sustain the weight of PV glass panels over larger areas, they are fully recyclable and free of toxic components such as potentially hazardous per- or polyfluoroalkyl substances (PFAS). Read more.

Photovoltaic encapsulant film: SABIC Fortify (POE) elastomers used for encapsulant films in bi-facial high-power glass-glass PV panels combine outstanding stability at elevated temperatures and UV exposure with improved potential induced degradation (PID) performance compared to commonly used EVA (ethyl vinyl acetate) based encapsulants. PID performance of SABIC’s elastomers for encapsulants in PV panels help the power of the module over time, maintaining low leakage current, thus extended service life. Read more.

Pipe solutions
Growing population and urbanization is increasing the demand for safe and secure potable water, sanitation, fluid and other critical piping above ground or below. SABIC offers material solutions that are more sustainable by increasing the performance and lifetime of pipes used in infrastructure, industrial, domestic and agricultural market areas. Read more.

Domestic: SABIC polyolefins have a proven fit in domestic piping. Newly developed grades support the growing need for more reliable, safe and cost-effective pipe systems in clean water supply, waste water discharge, heating and cooling installations.

Industrial: Pipes at industrial sites are often exposed to high pressures as well as aggressive fluids or abrasive substances. SABIC offers a range of polymer solutions tailored to meet these demanding challenges.

Infrastructure: To aid in the supply and distribution of renewable energy from solar and wind farms, underground power lines are an attractive alternative to traditional overland lines. SABIC offers a custom solution for power cable ducts to help drive the change towards renewable energy. In addition, the company has developed a new biaxial pipe technology together with partners, offering up to 30% of material savings over incumbent polyolefin pipes and superior resistance to slow-crack growth, which facilitates cost-efficient trenchless installation across geographic landscapes.

Agri- and Aquaculture: Securing the efficient and reliable production of food across plantations, farms and large greenhouse operations requires modern irrigation systems, especially where crop water demand exceeds the average rainfall and precious fresh water resources must be preserved. SABIC HDPE materials enable the manufacture of long-lasting and dependable pipes and tapes used for pressure-and drip irrigation as well as for fish farm cages.

Structural glazing
Lexan solid and multiwall sheet solutions help architects, builders and contractors implement aesthetic, energy efficient, high-impact and cost-effective glazing concepts from urban infrastructure to stadium roofs. For roofs and skylights of high-rise buildings, strength, weight and transparency have long remained a challenge. Multiwall panels from SABIC’s Functional Forms business offer extremely lightweight and easy-to-handle solutions. The following product examples and many more are also included in the interactive virtual building Explorer at SABIC’s booth.

Solar control: Lexan Thermoclear Solar Control IR multiwall sheet delivers a unique combination of very high thermal insulation and solar control performance to enhance energy conservation, light transmission, aesthetics and comfort while providing high strength and stiffness and impact resistance. By allowing up to 90% of natural daylight to enter, the sheet also saves on electricity for artificial lighting.

Greenhouses: The broad portfolio of Lexan Thermoclear sheet for greenhouse glazing applications may help operators to achieve significant overall cost reductions, energy savings and improved yield of crops. Next to ease of installation, excellent thermal insulation and UV resistance, it is also available with proprietary Easy Clean and Dripgard coatings to reduce maintenance costs and prevent condensation damage of crops. Last but not least, Lexan Thermoclear sheet is also resistant to hail impact, which avoids the damaging of the greenhouse façade and roofing, resulting in lower insurance costs. Read more.

Façade claddings: Besides various Lexan Thermoclear sheet products for vertical building applications, Lexan Thermoclick sheet system was specifically developed to enable visually striking profile-free façade installations. The system consists of UV-protected multiwall sheet panels with a profiled tongue and groove connection for interlocking, which eliminates the need for additional vertical profiles. Read more.

Clariant Launches New Additives at K 2022 to Support Plastics Sustainable Evolution

Clariant Launches New Additives at K 2022 to Support Plastics Sustainable Evolution

  • Anti-scratch additive for PP & TPO formulations boost reuse potential of plastics used in consumer applications
  • Extend service life of agricultural mulch films with new light stabiliser solution
  • Novel bio-based lubrication and nucleation additive for polyesters in E&E and transportation sectors

K 2022 visitors can look forward to new Clariant additive solutions to progress more sustainable plastics and reduce resource use. New developments give applications greater resilience to support longer use and reuse on the path to circularity. Plus, solve production challenges while achieving better efficiency and lower carbon footprint during compounding and processing (Hall 8a Booth J11).

“By extending a product’s service life and by boosting reuse potential, the plastics industry can contribute positively towards reducing wasteful consumption, and increase circularity in key segments. Adopting ways to reduce material waste and energy use in production brings further sustainability advantages and improves product carbon footprint. With these new additives, including renewable-based solutions, in our portfolios, we’re excited to offer plastic processors and value chains more support to collaborate and further innovate together,” comments Martin John, Head of Advanced Surface Solutions at Clariant.

New anti-scratch additive to extend the service life of consumer goods
Surface aesthetics play a crucial role in the perceived quality of consumer goods. Clariant’s new renewable raw material-based anti-scratch additive for polypropylene (PP) and thermoplastic olefins (TPO) formulations – Licowax AS 100 TP – enables molded plastic goods across a wide range of consumer applications to maintain their original look and feel for longer. This offers significant potential to extend service life and improve properties’ retention and parts’ reuse.

The new additive helps to prevent scratches and mars on the surface of goods during handling, transportation, and end-use. This is particularly beneficial for otherwise scuff-prone applications such as interior automotive parts like dashboards and door panels, household appliance casings, cosmetics packaging, and lightweight luggage.

New light stabilizer supports more sustainable agricultural films
Mulch films perform an important role in optimizing crop growing conditions, by protecting both crops and soil from contamination and from the loss of moisture and nutrients that could jeopardize yields. New AddWorks AGC 970, Clariant’s latest light stabilizer solution for polyethylene agricultural films, offers the mulch segment a step up in product durability. Addition of the additive enables converters to extend the service life of their products, in particular by increasing UV resistance and resistance to high levels of agrochemicals. The granular additive can be dosed directly during conversion which supports more tailored use.

New bio-based wax for reduced cycle times & easier processing of injection molded polyester compounds
Benefit from a unique combination of lubrication and nucleation in engineering plastics for greater efficiency in compounding and processing. Compared to more conventional products, new bio-based Licocare RBW 560 TP Vita is able to withstand higher processing temperatures thanks to excellent thermal stability and low volatility, and works more effectively at low dosage. It also has outstanding color stability. The combined benefits make it particularly attractive to formulators of polyester compounds for use in the E&E or transportation industries.

The new additive promotes easier mold release which improves the surface quality. Productivity-wise, it also means fewer polyester parts get stuck in the mold and therefore less injection molding downtime. The risk of short shots and rejects is reduced too. It is possible to produce more parts per machine hour due to faster cycle times driven by shorter cooling cycles. As a result, energy consumption is reduced.

Licocare RBW 560 TP Vita is the latest extension to Clariant’s Licocare range of high-performing additives based on renewable, non-food-competing feedstock. They are derived from crude rice bran wax, a by-product from the production of rice bran oil. Vita designated products use real renewable content of at least 98% Renewable Carbon Index (RCI), thus offering the advantage of a lower carbon footprint compared to state-of-the-art alternatives.

Clariant has submitted an application for FDA food contact approval for its entire range of Licocare RBW additives. This will open up their use by plastics compounders and masterbatch producers in an even wider range of plastics applications.

Clariant’s additive products and solutions offer exciting opportunities for the plastics industry to strengthen the links between efficiency and sustainability, safety and performance, value and low carbon footprint. For more information on these featured new additives, as well as Clariant’s wider support to meet sustainability and circular economy challenges, meet the team at K 2022 Hall 8a Booth J11.

Reifenhäuser Extrusion Systems and Maku AG Enter Into Strategic Partnership for Automation System in the Field of Slot Dies and Coextrusion Adapters

Reifenhäuser Extrusion Systems and Maku AG Enter Into Strategic Partnership for Automation System in the Field of Slot Dies and Coextrusion Adapters

Reifenhäuser Extrusion Systems (RES) – the Reifenhäuser Group’s business unit specializing in extrusion components – announces a strategic partnership with maku AG at K 2022, the world’s largest plastics trade fair. The aim of the cooperation is the joint marketing and further development of the automation system designed by maku for coextrusion adapters and slot dies.

The so-called PAM system (precise, autonomous, mechatronic) is available immediately and exclusively as an automation option for new Reifenhäuser dies and adapters, as well as for aftermarket dies across all manufacturers. PAM enables producers in the field of flat film and sheet production as well as extrusion coating to precisely control the entire hot part (coextrusion adapter and die) via the line’s control panel. This is significantly faster and more accurate than conventional control by hand or expansion bolt automation. It enables faster start-up of good production, higher output with lower energy consumption, and thus significantly improved overall equipment efficiency (OEE). The decisive advantage lies in the use of motorized manual adjustment bolts that replace conventional thermal expansion bolts. Reifenhäuser presented the system for the first time at the K 2022.

Uwe Gaedike, Managing Director of Reifenhäuser Extrusion Systems, explains, “The technology and experience of maku ideally completes our hot part competence. As RES, we manufacture extruder, coextrusion adapter and die completely in-house and thus know the entire extrusion process. With the automation option, we can now offer our customers a perfectly coordinated overall system that is second to none. Together with maku, we will establish the technology in the market and continuously develop it further. The special thing about this is that we also offer it as part of our refurbishment portfolio for all lines in the market.”

 

PAM coextrusion adapters automate the setting of the layer distribution.

 

Reto Maeder, Managing Director and Co-Owner of maku AG, adds, “We are very pleased to have found a strong partner in Reifenhäuser to now market our technology even more effectively globally. Together we will exploit the full potential of our cross-process know-how and create clear competitive advantages for our customers. This is nothing less than the best hot part competence combined with the highest possible level of automation in the market. At the same time, maku AG will continue its classic retrofit business on existing dies unchanged. Reifenhäuser’s worldwide service network puts us in a position to offer our system to even more customers outside
Europe.”

 

The decisive advantage of PAM dies lies in the use of motorized manual adjustment bolts that replace conventional thermal expansion bolts.

Upcycling of Polyolefins With Innovative Stabilizers

Upcycling of Polyolefins With Innovative Stabilizers

At K 2022, Brüggemann will present three new additives for improved stabilization of polyolefin recyclates. These additives result in recyclates with very good mechanical and processing properties, making the need for the addition of virgin material unnecessary. All Bruggolen R grades are supplied as dust-free additive blends in compacted granule form for easy and homogeneous distribution.

Two of the new stabilizers are intended for polypropylene recycling. Bruggolen TP-R2090 can be used to recycle post-industrial and post-consumer waste, whereas Bruggolen TP-R8895, through its increased acid scavenger content, is especially suitable for recycling polypropylene from battery cases. Both additives result in recyclates of quality that cannot be achieved via conventional re-stabilization.

For polyethylene recycling, Brüggemann has developed Bruggolen TP-R2162, which also contains the new repair technology and is particularly suitable for LLDPE recyclates used in film extrusion. Here, the repair mechanism results in film with increased initial mechanical strength and a significantly reduced number of defects. Laboratory tests, for example, show an increase of around 25% in tensile strength and 10% in elongation at break, even at minimal dosage levels of 0.3%.

These outstanding properties of the polyolefin recyclates are made possible by a specially developed technology. For the first time, it is possible to repair defects to the molecular chains that occur during processing and subsequent use and which impair quality. The recyclate is not only protected from further damage by re-stabilization, but, by repairing the polymer chains, the resultant mechanical strength more closely matches that of virgin polymer.

With the newly introduced Bruggolen R grades, Brüggemann complements its broad portfolio of additives for mechanical recycling of polyamides. These include long-term heat stabilizers, process stabilizers, flow improvers, reactive chain modifiers, nucleating agents and other process auxiliaries.
