Thermoplastic vulcanizates (TPV) below to the thermoplastic elastomer family. TPVs are chemically crosslinked rubber, mainly EPDM, in a thermoplastic polymer where the rubber may be partially or fully crosslinked. TPVs have the functional performance of conventional thermoset rubbers but with the processability of thermoplastics. TPVs have a number of excellent characteristics including excellent low compression set, good dynamic fatigue resistance, elastic recovery, temperature resistance, chemical resistance and easy processability. Typical applications for TPVs include seals and gaskets, CJV boots, wire and cable, tubing, pads and bumpers, food closures, grips and handles, weatherstripping, window glazing and automotive interior parts.
