From the Sector

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

Flax has accompanied people for thousands of years, in linen fabrics, in ropes, as insulation material. And until the present day. With woven tapes made of flax, vombaur makes the functional and ecological advantages of natural fibres available for lightweight design.

Lightweight and firm
Flax fibres are particularly rigid and tear-proof. Textiles made of the natural material therefore give natural fibre reinforced plastic (NFP) special stability. Additionally, flax has a low density. The components thus combine high rigidity and strength with low weight. Another functional plus: natural fibre reinforced plastics are less prone to splintering than glass fibre reinforced plastics.

Sustainable material
The cultivation of flax binds CO2 and the production of NFP generates 33 percent lower CO2 emissions than conventional fibre reinforced plastics. The energy consumption is 40 percent lower. This reduces production costs and improves the material's CO2 footprint. Punch-packing arguments for natural fibre tapes – like flax tape by vombaur – in lightweight design applications.

Circular Economy
Circular Economy – this also works in lightweight design. The number of recycling cycles without loss of quality is higher for natural fibre reinforced plastics than for glass or carbon fibre reinforced plastics: the thermoplastic matrix of the composite can be melted and recycled after a product life cycle. The natural fibres can "live on" in other products – injection moulded products for example.

Versatile applications
"Composites from our flax tapes are used to reinforce high-tech skis as well as for extruding state-of-the-art window sections – the applications are countless," explains Tomislav Josipovic, Sales Manager with vombaur. "As a development partner, we support applications for the automotive, wind energy, construction, sports and many other industries with our composite textiles."

By capitalising on its profound expertise in virgin polyolefins and collaborating with value chain partners, Borealis keeps discovering new opportunities for business growth within the circular economy.

Advancing technology to bring about polyolefin circularity

The new technology, Borcycle, transforms polyolefin-based waste streams into recyclate material such as pellets. As a transformative technology, it complements the existing Borealis virgin polyolefins portfolio with a range of pioneering, circular solutions. It unites state-of-the-art technology with the profound Borealis polymer expertise gained over decades.

As a scalable and modular technology, Borcycle has been developed to meet growing market demand for high-quality recyclate. Leading appliance brand owners, for one, have pledged to increase the amount of recycled plastics in their goods. Yet until recently, producers have not been able to rely on a consistent supply of high-quality recyclate. The Borcycle technology will help address this challenge. Compounds made using the Borcycle technology deliver high performance, add value and offer versatility. Producers and brand owners in a range of industries will profit from the availability of high-quality recyclate that helps them meet environmental and regulatory challenges.

“Advancing technology is crucial if our aim is to implement value-creating solutions in the circular sphere,” claims Maurits van Tol, Borealis Senior Vice President, Innovation, Technology & Circular Economy Solutions. “‘Building tomorrow together’ means innovating, collaborating, focussing on the customer, and above all – taking action.
