The versatile, resilient, durable copolyester

Hytrel® drives innovative design, enabling the development of unique parts with superior performance characteristics. This versatile material can flex in multiple directions, cycle after cycle, long after rubber would break. Its durability has made it an essential ingredient in automotive components such as Constant Velocity Joint (CVJ) boots, which must endure a wide range of temperatures and tough conditions over the life of a vehicle.

Hytrel® TPC-ET thermoplastic elastomer combines the flexibility of rubber with the strength and processability of thermoplastics. Manufacturers prefer parts made with Hytrel® for their resilience and heat and chemical resistance, as well as their strength and durability.


Setting new standards for functional sustainability

All Hytrel® ECO B materials are produced in a plant powerd by electricity from 100% renewable sources. Plus, this innovative thermoplastic elastomer uses up to 72% second-generation biomass, enables over-molding on rigid thermoplastics, and allows rework and recycling of scrap.



Flexibility and resilience icon

Flexibility and resilience

Hytrel® flexes and recovers, providing excellent flex fatigue and tear resistance, low hysteresis and spring-like properties. 

Strength and abrasion resistance icon

Strength and abrasion resistance

Hytrel® offers exceptional toughness, impact and creep resistance.

 Easy processing (wide process window with thermal stability) icon

Easy processing

Hytrel® can be processed by injection, blow or rotational techniques; it can be extruded into tubes, profiles, fibers/filaments, sheet, blown or cast film, web coating, nonwovens and wire and cable jacketing.

Broad service temperature (-40°C to 150°C) icon

Broad service temperature

Flexibility at low temperatures, and good retention of mechanical properties at high temperatures.

Chemical resistance (to hydrocarbons & other fluids) icon

Chemical resistance

Hytrel® stands up to oils, fuels, hydrocarbon-based solvents, and many other chemicals.

Enables over-molding and innovative designs icon

Enables over-molding and innovative designs

Hytrel® is compatible with other thermoplastics such as PC, ABS and polyesters, allowing over-molding and coextrusion. 

Allows rework and recycling icon

Allows rework and recycling

The exceptional melt stability and thermoplastic nature of Hytrel® allow the recycling of processing scrap. Hytrel® can be reground and blended with virgin polymer.
