Details

Arnitel® is a high-performance thermoplastic copolyester (TPC) that offers a unique combination of flexibility, high temperature resistance and strength with excellent processing characteristics, making it a reliable solution for inboard and outboard boots, prop shaft boots, CVJ, constand velocity joints, and steering bellows. Compared to rubber, Arnitel® TPC is 75% lighter and offers 50% lower system costs. Arnitel® TPC is a plasticizer free solution making it a sustainable choice. It also offers peak temperature resistance of up to 180° C – 200° C and good heat aging due to continuous use temperatures of 120° C – 170° C. Arnitel® TPC also offers good resistance against chemicals and greases.
