Brand Information

Arnitel®

Arnitel® TPV, produced by Envalior, is a family of thermoplastic copolyester-based elastomers (TPV’s or COPE) that combine the strength and processing characteristics of engineering plastics with the performance of thermoset elastomers, providing benefits in processing and productivity. These copolyesters do not require vulcanisation to obtain their optimal properties, leading to substantial reductions in part cost.
