Abstract
A thermoplastic elastomer composition for a powder material used for slush molding. The thermoplastic elastomer composition consists of a polypropylene resin and 20 to 500 parts by mass of a hydrogenated block copolymer per 100 parts by mass of the polypropylene resin. The hydrogenated block copolymer has a) at least one polymer block A with a primary component that is a vinyl aromatic hydrocarbon monomer unit and b) at least one polymer block B with a primary component that is a hydrogenated butadiene monomer unit. The polymer block B has a hydrogenation degree of at least 90%. The vinyl aromatic hydrocarbon in the hydrogenated block copolymer is present in an amount more than 5 mass % and less than 25 mass %. The polymer block B before hydrogenation contains 62 mol % or more 1, 2 bonds on average. The melt flow rate (MFR) of the thermoplastic elastomer composition is at least 10 g/10 min at 230° C. under a load of 2.16 kgf in accordance with Japanese Industrial Standards (JIS) K7210.
