ÜBERZUG FÜR AIRBAGVORRICHTUNG MIT EINER THERMOPLASTISCHEN ELASTOMERZUSAMMENSETZUNG

摘要

Disclosed is a thermoplastic elastomer composition comprising 100 parts by weight of a mixture of two different specific hydrogenated block copolymers which are different in molecular structure and number average molecular weight; 25 to 60 parts by weight of a polyolefin resin having a melt flow rate of from 5 to 50 g/10 minutes; and 0 to 30 parts by weight of a hydrocarbon oil. The thermoplastic elastomer composition of the present invention has excellent softness, heat resistance, low-temperature characteristics, weatherability, mechanical strength, moldability and scratch resistance. Also disclosed is a cover for an air bag device, which comprises a molded body formed by molding the thermoplastic elastomer composition.
