Arnitel® PL381

Technical Datasheet | Supplied by Envalior
Arnitel® PL381 by Envalior is a high-performance, non-reinforced & non-flame retardant, thermoplastic copolyester (TPC). It is a lighter, smarter, greener alternative to conventional rubbers thus, reducing environmental impact. It has good colorability with a stable white base color. It possesses flexibility, strength, excellent processing characteristics. It is processed by injection molding. This grade shows high temperature resistance, good elasticity and good spring characteristics. It offers low hysteresis, chemical resistance against household chemicals like cleaning agents, sunscreen lotion and automotive greases and oils. It offers intrinsic breathability. It allows for the possibility to run at lower film thickness and at higher extrusion speed versus TPU, which allows for a lower cost system. Arnitel® PL381 is used in house wrap and soap dispensers applications. It meets ISO 18064 for TPC-ET.
