摘要：
A thermoplastic elastomer moulding composition having a Shore A hardness of less than 45 comprises:
100 parts by weight of a selectively hydrogenated block copolymer comprising aromatic monoalkenyl or monoalkenylidene hydrocarbon polymer blocks and partially or completely hydrogenated aliphatic conjugated diene hydrocarbon polymer blocks,
50 to 400 parts by weight of an oil-extended olefinic copolymer rubber partially crosslinked with
2 to 100 parts by weight of a polyolefin resin, and
50 to 350 parts by weight of a mineral oil type softening agent.
