Arnitel® PL380

Technical Datasheet | Supplied by DSM
Arnitel® PL380 by DSM is a high-performance, high flow, non-reinforced & non-flame retardant, thermoplastic copolyester (TPC) grade. It is a lighter, smarter, greener alternative to conventional rubbers thus, reducing environmental impact. It is processed by injection molding. It possesses flexibility, strength and excellent processing characteristics. This food contact quality grade shows high temperature-, fatigue- and abrasion resistance. It offers chemical resistance against household chemicals like cleaning agents, sunscreen lotion and automotive greases and oils. It allows for reliable solutions due to excellent colorability and color stability and due to its retention of flexibility even at temperatures down to -40°C or at elevated temperatures up to 100˚C. And, allows for solutions with nice touch & feel characteristics. Arnitel® PL380 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 exhibits excellent load bearing capacity and environmental resistance and due to a very consistent performance over temperature ranges from -55°C (-67°F) to +150°C (+300°F) and longest lifetime to failure. It is used in bed springs, railway pads and suitcase handles. It meets ISO 18064 for TPC-ET.
