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.
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 and heat and chemical resistance, as well as their strength and durability.
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.
Hytrel® flexes and recovers, providing excellent flex fatigue and tear resistance, low hysteresis and spring-like properties.
Hytrel® offers exceptional toughness, impact and creep resistance.
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.
Flexibility at low temperatures, and good retention of mechanical properties at high temperatures.
Hytrel® stands up to oils, fuels, hydrocarbon-based solvents, and many other chemicals.
Hytrel® is compatible with other thermoplastics such as PC, ABS and polyesters, allowing over-molding and coextrusion.
The exceptional melt stability and thermoplastic nature of Hytrel® allow the recycling of processing scrap. Hytrel® can be reground and blended with virgin polymer.
Based on a biomass approach, the newest Hytrel® grades are true drop-in replacements with no need to requalify products or retool.
Hytrel® is a plasticizer-free thermoplastic polyester elastomer with outstanding flexibility, stable mechanical performance over a wide temperature range, and straightforward processing characteristics.
With Shore D hardness of 30 to 80, Hytrel® bridges the performance of rubbers and thermoplastics.
Hytrel® offers grades for food contact, and special and premium control grades for medical applications.
High-viscosity Hytrel® is ideal for blow molding and extrusion, allowing for efficient production.
Hytrel® allows advances in the design of injected parts, extruded films and filaments, foams, and more.
Hytrel® ECO B, with up to 72% biomass, helps improve the environmental footprint of your products.
