An Assessment of Recently Developed Thermoplastic Polyurethane and Polyester Elastomers.

Abstract

The processing characteristics and ageing properties of thermoplastic, injection molded polyurethane and polyester copolymer elastomers are assessed. The ageing properties of the polyurethanes show little improvement compared with cast and millable polyurethane elastomers, although their processibility is easier and they can be more economical for the production of large numbers of small components. The polyester copolymers have very good mechanical and ageing properties and should be considered as serious candidates for replacing conventional elastomers in many high performance applications.
