Patent ID: 8022128

Claim:
A thermoplastic elastomer composition comprising: (A) about 25 to about 55 parts by weight of block terpolymer including an aromatic vinyl compound and an alkene compound, wherein said block terpolymer (A) is a A-B-A′ block terpolymer, wherein each of the A and A′ blocks are a hard segment, the B block is a soft segment, and the terpolymer comprises the hard segments in an amount of about 20 to about 35% by weight and the soft segment in an amount of about 65 to about 80% by weight; (B) about 20 to about 50 parts by weight of a paraffin oil; (C) about 5 to about 15 parts by weight of a polyolefin resin; (D) about 5 to about 20 parts by weight of a inorganic additive; and (E) about 3 to about 15 parts by weight of a polyphenylene ether, wherein said thermoplastic elastomer composition has a surface hardness of about 50A (shore A) or less and has an elongation permanent set (100° C.) of about 5 to about 13%.
