Hytrel
From Plastics Wiki, free encyclopedia
Hytrel® is a theromoplastic polyester elastomer manufactured by Dupont [1]. Hytrel® gives the flexibility of rubbers, the strength of plastics, and the processibility of thermoplastics and can be processed easily by conventional thermoplastic processes like injection molding, blow molding, calendaring, rotational molding, extrusion and meltcasting.
Applications
Hytrel® is designed for applications requiring excellent flex fatigue and a broad temperature range. It has strong resistance to tearing, flex-cut growth, creep and abrasion. Its mechanical properties provide strength and stiffness, in addition to outstanding toughness. Chemically, it is highly resistant to hydrocarbons.
Dupont supplies Hytrel® grades in a full range of Shore D hardnesses from 30D to 82D. Heat stabilized, flame retardant, and blow molding grades are also available. Concentrates offered include black pigments, UV protection additives, hydrolysis resistant additives, heat stabilizers, and flame retardants.
