Hytrel® TPC-ET thermoplastic polyester elastomer

A Thermoplastic Elastomer Engineered for Versatile Performance

Hytrel® combines the flexibility of rubber with the strength and processability of thermoplastics.

DuPontTM Hytrel® TPC-ET thermoplastic elastomer is a versatile copolyester. It combines resilience, and heat and chemical resistance with strength and durability.

Parts made with Hytrel® thermoplastic elastomer resin can flex in multiple directions, cycle after cycle, long after rubber would break. A prime example is the Constant Velocity Joint (CVJ) boot, an automotive component that is subject to an average of 150,000 miles of pounding, and a wide range of temperatures.

Hytrel® is an excellent choice when innovative new designs require creation of unique parts with multiple performance characteristics, since it can be processed using many thermoplastic methods. When renewably sourced materials are a priority, DuPontHytrel® RS offers the same performance as Hytrel® while containing 20% to 60% of renewably sourced material from non-food biomass.
