Hytrel, copolyester elastomer

The effect of °Co y-ray irradiation on the mechanical properties, surface morphology, and fractography of blends of plasticized PVC and thermoplastic copolyester elastomer, Hytrel (E.I. Du Pont de Nemours Company, Inc., Wilmington, Delaware), have been studied by Thomas et al. [445]. Radiation has two major effects on the blend cross-linking of the Hytrel phase and degradation of PVC phase. Both effects are found more prominent at higher radiation dose. 

Du Font s Hytrel copolyester thermoplastic elastomers are slightly higher in price than the polyurethane types and have grown rapidly. They have a wide range of service temperatures and have found major uses in recreational vehicles, belting, hydraulic hose, and mechanical goods.
