ABSTRACT:
Thermoplastic compositions of matter useful as gasketing materials as well as flexible boots and seals which are soft, have low compression set and high tensile. The compositions comprise a polyolefin resin and at least two different rubbers, one of which is vulcanized to a fully cured state by a cure system which leaves the other rubber(s) unvulcanized. The preferred embodiment comprises a blend of polypropylene and ethylene vinylacetate as the polyolefin resin component, EPDM as the uncured rubber component and a ZnO cured halogenated butyl rubber. In another embodiment of the invention, the resin is excluded and the uncured rubber is a high crystallinity EPDM.
