Abstract
Disclosed is a casing for storing an airbag for an airbag restraint system, cavingg: a main body formed of a material comprising a thermoplastic elastomer composition which is prepared by: mixing 100 parts by weight of a copolymer composition with 0.05 to 0.5 parts by weight of a lubricant comprising higher fatty acid amide to obtain a mixture; and dynamically heat-treating the mixture in the presence of an organic peroxide and an auxiliary crosslinking agent. The copolymer composition contains: (A) 20 to 50 parts by weight of an olefin copolymer resin of propylene and one or two kinds of 1-olefin other than propylene; (B) 10 to 50 parts by weight of ethylene-propylene copolymer rubber having a Mooney viscosity (ML,, 100° C.) ranging from 30 to 60; (C) 10 to 70 parts by weight of ethylene-propylene-nonconjugated diene copolymer rubber having a Mooney viscosity (ML,, 100° C.) ranging from 50 to 100; and (D) 10 to 50 parts by weight of an oil-extended ethylene-propylene-nonconjugated diene copolymer rubber containing ethylene-propylene-nonconjugated diene copolymer having a Mooney viscosity (ML,, 100° C.) ranging from 150 to 350 and a mineral oil softener contained at an amount of 50 to 150 parts by weight relative to 100 parts by weight of the ethylene-propylene-nonconjugated diene copolymer.
