An airbag housing cover comprising a thermoplastic elastomer composition comprising a propylene-based polymer, an elastomer, and a colorant,
- wherein the thermoplastic elastomer composition has a total light transmittance of 0.001% or more and 70% or less as measured by injection molding the thermoplastic elastomer composition under conditions of a resin temperature of 200° C. and a mold temperature of 40° C. to produce a sheet-like test piece having a thickness of 1 mm, and measuring the total light transmittance of the sheet-like test piece according to JIS K7136-1.
A thermoplastic elastomer composition comprising a propylene-based polymer, an elastomer, and a colorant,
- wherein the elastomer comprises at least one selected from the group consisting of a styrene-based elastomer and an ethylene-α-olefin copolymer,
- the colorant comprises at least one selected from the group consisting of an organic pigment and an inorganic pigment, and
- the thermoplastic elastomer composition has a total light transmittance of 0.001% or more and 70% or less measured by injection molding the thermoplastic elastomer composition under conditions of a resin temperature of 200° C. and a mold temperature of 40° C. to produce a sheet-like test piece having a thickness of 1 mm, and measuring the total light transmittance of the sheet-like test piece according to JIS K7136-1.
