description | PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition for air bag covers which shows reduced molding shrinkage and reduced thermal shrinkage, as it holds its conventional properties. SOLUTION: This composition comprises the crystalline propylene polymer part and the non-crystalline propylene-ethylene copolymer part, contain 30-50wt.% of propylene-ethylene copolymer containing 10-50wt.% of the copolymerization part, 10-60wt.% of linear low-density polyethylene which has a density of 0.860-0.905g/cm , a melt index of 0.1-50g/10min and the ratio of the weight average molecular weight/the number-average molecular weight of 1.8-2.8 and contains >=20% of an α-olefin comonomer of 4-8 carbon atoms and 10-60wt.% of an ethylenic copolymer rubber or a polyethylene with a density of 0.92-0.96g/cm . |
