摘要：
A thermoplastic elastomer (TPE) composition is provided which has a first high vinyl styrenic block copolymer (SBC) having a number average molecular weight (Mn) less than about 120,000 Daltons (Da) and a second high vinyl SBC having a Mn greater than about 120,000 Da; a polyolefin; and a plasticizer compatible with the first and second SBCs. An article formed from such a TPE composition has a tensile strength greater than 600 psi, a hardness less than 45 Shore A, and a haze less than 20 percent, preferably less than 15 percent, when the thickness of the article is 1.7 mm, and wherein the physical dimensions of the article remain substantially unchanged after immersion of the article in boiling water for one hour.
