Asahi Kasei presents diversified material solutions for EV batteries and circular economy

Japanese technology company Asahi Kasei will showcase diversified material solutions for safe and compact EV batteries, improved connectivity and lightweighting, as well as circular economy at Fakuma, an event for industrial plastics processing, from 17 – 21 October 2023 in Frie-drichshafen, Germany.     

Thermoplastic composites for EV battery applications:

This year, Asahi Kasei will put a special focus on its broad range of materials for lightweight, compact, and safe electric vehicle battery solutions. The company is currently developing a new continuous glass fiber reinforced thermoplastic, LENCEN™, and will present it for the first time at the European trade show #Fakuma. This composite material is formed by stacking layers of continuous glass fiber textiles with #polyamide66 (PA66) films. Due to its tensile strength, high heat resistance, and impact properties similar to metal, this material improves collision safety and weight reduction of EV batteries.

In addition, the company will showcase a carbon fiber reinforced thermoplastic unidirectional tape (CFRTP-UD tape) that utilizes both recycled continuous carbon fiber and the company’s LEONA™ polyamide resin. Boasting a higher strength than metal, this CFRTP-UD tape can be applied to automobile frames and bodies, further enabling the recycling of end-of-vehicle-life parts into different, new automobile parts.

Asahi Kasei will also showcase #coolingpipes for #EVbattery packs made of the modified #polyphenyleneether (m-PPE) XYRON™, as well as 2170 cell trays based on the m-PPE particle foam SunForce™.

Solutions for improved HMI and glass replacement

AZP™ is a #transparent polymer that overcomes the disadvantages of conventional optical plastic materials. Featuring a close-to-zero #birefringence equivalent to glass as well as a superior designability, this material allows high transmittance and low color distortions at all viewing angles. Clear images without luminance variations, color distortion and blurring can be achieved in polarized optical equipment such as AR/VR headsets and head-up-displays (HUDs). The premium quality appearance is also maintained when looking at the display through polarized #sunglasses.

Bio-based feedstock and new recycling technology for PA66

#AsahiKasei will display a #biobased and #biodegradable #cellulosenanofiber (CNF). This material is made from #cotton linter and features a high heat resistance and network-forming ability. CNF-reinforced polyamide shows a thixotropic behavior, making it highly suitable for #3dprinting applications in terms of easy printing, dimensional accuracy, smooth appearance, and mechanical performance. Furthermore, CNF has superior material recyclability compared to glass fibers.

Cleaning the equipment after processing the plastics in an efficient and cost-effective manner is a major challenge for many companies. Asaclean™ is the worldwide leader in commercial purging compounds. Asaclean™ purges are optimized for injection molding, extrusion, film and sheet, blow-molding, and blown-film applications. Its benefits include faster changeovers/reduced downtime, effective removal of color/carbon contamination, reduced screw-pulls, lower scrap/reject rate, increased productivity, and greater cost savings.

The company will also present its comprehensive solutions for establishing a sustainable life cycle for PA66 utilizing bio-based feedstock and a new technology for chemical recycling. Together with Japanese partner company Microwave Chemical, the company is working on a new technology for chemical recycling of PA66. The process utilizes microwaves to depolymerize automotive airbags and
other PA66 parts and directly obtain the monomers hexamethylenediamine (HMD) and adipic acid (ADA), which is expected to be accomplished at high yield with low energy consumption. The monomers obtained can then be used to manufacture new PA66.
