Patent ID: 7491757

Claim:
A fully vulcanized thermoplastic elastomer, comprising a rubber phase and a plastic matrix, wherein an average particle size of the rubber phase of said fully vulcanized thermoplastic elastomer is 0.02μ˜1μ, wherein a shape of the rubber phase of said fully vulcanized thermoplastic elastomer is spheroidic, wherein the weight ratio of the rubber phase to the plastic matrix is 30:70 to 75:25, wherein the rubber phase of said fully vulcanized thermoplastic elastomer comprises at least one rubber selected from the group consisting of natural rubber, styrene-butadiene rubber, carboxylated styrene-butadiene rubber, nitrile rubber, carboxylated nitrile rubber, polybutadiene rubber, chloroprene rubber, silicone rubber, acrylic rubber, styrene-butadiene-vinylpyridine rubber, isoprene rubber, butyl rubber, polysulfide rubber, acrylic-butadiene rubber, polyurethane rubber, and fluorine rubbers, and wherein the rubber phase is provided by a fully vulcanized powdery rubber prepared by vulcanizing a corresponding rubber latex with irradiation.
