The Japanese technology company Asahi Kasei recently signed a memorandum of understanding (MOU) with Aquafil S.p.A., an Italian manufacturer of polyamide 6 (PA6). The two companies agreed to develop a novel material for 3D printing (3DP) applications utilizing Aquafil’s ECONYL® Polymer chemically recycled PA6 and Asahi Kasei’s cellulose nanofiber (CNF), with the support of ITOCHU Corporation, which has made a capital investment in Aquafil. Pellets or filaments of this compound achieve superior formability and strength, which make them suitable for use in automotive and aeronautical applications.
ECONYL® Polymer is a chemically recycled PA6 derived from post and pre-consumer waste. Utilizing polyamide waste such as used fishing nets, old carpets, industrial waste and so on, the material is first depolymerized into monomers, and then re-polymerized into ECONYL® Polymer chips.
Asahi Kasei’s CNF is made from cotton linter and features high heat resistance and network-forming ability. Furthermore, CNF has superior material recyclability compared to glass fiber. The new CNF/ECONYL® Polymer compound features excellent formability and strength especially in 3DP usage, and Asahi Kasei sees a great potential in high-performance applications mainly in the automotive and aeronautical fields. Asahi Kasei plans to begin trial sales of filament of the new compound material in the EU, US, and Japan in Q3 2025.
