Hytrel® RS Renewably Sourced Thermoplastic Elastomers can help reduce environmental footprint without compromising performance.

Grades containing 35% to 65% renewably sourced material show the same performance and processing characteristics of original Hytrel®. Properties and Processing information for Hytrel® RS.

Hytrel® is ideal for parts requiring excellent flex fatigue and broad use temperature. It resists tearing, flex-cut growth, creep and abrasion. It offers strength and stiffness plus outstanding toughness while resisting hydrocarbons and many other fluids.Hytrel® can be processed easily by conventional thermoplastic processes, such as injection molding, blow molding, calendaring, rotational molding, extrusion and meltcasting.
