DuPont Hytrel TPC-ET thermoplastic elastomer The versatile, resilient, durable copolyester
DuPont 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, heat and chemical resistance, as well as their strength and durability.
DuPont Hytrel drives innovative design, enabling the development of unique parts with multiple performance characteristics. This versatile thermoplastic elastomer resin 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 the Constant Velocity Joint (CVJ) boot, which must endure an average of 150,000 miles of pounding over a wide range of temperatures.
DuPont Hytrel RS delivers all of the benefits of Hytrel®, yet it contains up to 60 percent renewably sourced materials from biomass, making it an excellent product for applications demanding renewably sourced options.

Advantages
Flexibility and resilience
DuPont Hytrel flexes and recovers, providing excellent flex fatigue and tear resistance, low hysteresis and spring-like properties.
Strength and abrasion resistance
DuPont Hytrel offers exceptional toughness, impact and creep resistance.
Easy processing
DuPont Hytrel can be molded by injection, blow or rotational techniques; it can be extruded into tubes, profiles, fibers/filaments, sheet, blown or cast film, web coating, nonwovens, wire and cable jacketing.
Broad service temperature
Flexibility at low temperatures, and good retention of mechanical properties at high temperatures.
Chemical resistance
DuPont Hytrel stands up to oils, fuels, hydrocarbon-based solvents, and many other chemicals.
Enables over-molding and innovative designs
DuPont Hytrel is compatible with other thermoplastics such as PC, ABS and polyesters, allowing over-molding and coextrusion.
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.
