Toyobo Pelprene™ P-280B Polyester TPE
Categories: Polymer; Thermoplastic; Elastomer, TPE; Polyester, TP; Polyether Ester Elastomer
Material Notes: Key Feature: Pelprene P type

Pelprene™ can be processed into a wide variety of articles from ultra-small precision parts to sheets by injection, extrusion, and blow molding. The 'P' type is a block copolymer consisting of an aromatic polyester as the hard segment and an aliphatic polyether as the soft one. It covers general purpose grades, being designed to have a balance of flexibility, heat & cold resistance, chemical resistance, and processability.
