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.
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.
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 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.
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.
Hytrel® is a plasticizer-free thermoplastic polyester elastomer that offers an outstanding combination of flexibility, stable mechanical performance over a broad temperature window, straightforward processing characteristics and other properties.
With a Shore D hardness ranging from 30 to 80, Hytrel® bridges the mechanical performance of rubbers and thermoplastics. Further tuning of Hytrel® properties is achievable by addition of pigments and/or concentrates to reach the targeted performance for a specific application.
Hytrel® includes grades for food contact applications as well as special and premium control grades for medical applications with superior testing, manufacturing control and regulatory support.
•High viscosity Hytrel® grades developed for blow molding and extrusion allow the efficient production of automotive parts, wires and cables, and other applications.
Hytrel® enables the design and economical manufacture of solutions combining the features of high-performance elastomers and flexible plastic materials. In addition to injected parts, Hytrel® applications include extruded films and filaments, foams and more.
