HYTREL
Hytrel is actually the DuPont registered trademark for its engineering thermoplastic elastomers. The polyether-ester block copolymers combine many of the most desirable characteristics of high-performance elastomers and flexible plastics. Hytrel offers a unique combination of mechanical, physical and chemical properties that qualifies it for demanding applications. The various grades of Hytrel exhibit a wide range of flexibility or stiffness and processing capabilities. Certain properties of Hytrel that makes it stand above other types of nylons are :
Hytrelcan be readily formed into high-performance products by a variety of thermoplastic processing techniques, including injection molding, extrusion, blow molding, rotational molding and melt casting. Hytrel is processed at temperatures between 177 and 260°C (350 and 500°F), depending on the process and polymer type. All standards grades have a sharp melting point and very good melt stability.
