Hytrel® thermoplastic polyester elastomers provide a winning combination for many parts and components. They give the flexibility of rubbers, the strength of plastics and the processibility of thermoplastics. They can be processed easily by conventional thermoplastic processes like injection molding, blow molding, calendaring, rotational molding, extrusion and melt casting.
Hytrel® is ideal for parts requiring excellent flex fatigue and broad use temperature. It is strongly resistant to tearing, flex-cut growth, creep and abrasion. Its mechanical properties provide the strength and stiffness you need, in addition to outstanding toughness. Its chemical properties make it highly resistant to hydrocarbons and many other fluids.
Hytrel® grades are available in a full range of Shore D hardness's from 30D to 82D. Special grades include heat-stabilized, flame-retardant, and blow-molding. Concentrates offered include black pigments, UV protection additives, hydrolysis-resistant additives, heat stabilizers and flame retardants
