Arnitel® PB420

Chemical Family: Polyesters

Arnitel® PB420 is a high-performance thermoplastic copolyester (TPC) that provides flexibility, high temperature resistance, and strength, along with excellent processing characteristics. It is increasingly used as a lighter, smarter, and greener alternative to conventional rubbers in industries such as automotive and E&E, reducing environmental impact and system costs. The material can be processed using blow molding technology.
