PURPOSE: To provide an air bag storage case excellent in appearance, low in cost and safe in spite of being single layer constitution. CONSTITUTION: 10-50 pts.wt. of polyolefine resin is mixed in 100 pts.wt. of olefine copolymer rubber with Mooney viscosity (ML1+4 , 100 deg.C) of 50-100, and heat treatment is dynamically applied under the presence of organic peroxide. A composition formed of 100 pts.wt. of a thermoplastic elastomer composition obtained by adding 5-50 pts.wt. of mineral oil group softener, and 20-50 pts.wt. of random copolymer resin composed of propylene with a melt flow rate (230 deg.C) of 30-100 and one or two kinds of 1-olefine other than propylene is formed to obtain an air bag storage case, and a specific skin layer is bonded to this case. |
