Arnitel® PL581

Technical Datasheet | Supplied by Envalior
Arnitel® PL581 by Envalior is a high-performance, non-reinforced & non-flame retardant, thermoplastic copolyester (TPC). It is processed by injection molding & extrusion. It is a lighter, smarter, greener alternative to conventional rubbers thus, reducing environmental impact. It possesses flexibility, strength & excellent processing characteristics. It offers chemical resistance against household chemicals like cleaning agents, sunscreen lotion and automotive greases and oils. It allows for cost effective solutions since it yields thermoplastic processing advantages over rubber, resulting in faster cycle times in comparison with other TPE's. It provides high abrasion resistance, excellent load bearing capacity and environmental resistance and very consistent performance over temperature ranges from -55°C (-67°F) to +150°C (+300°F) and longest lifetime. Arnitel® PL581 is used in railway pads applications. It meets ISO 18064 for TPC-ET.
