Thermoplastic elastomer composition for a powder for slush molding and skin formed therefrom |
摘要 |
<p>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 (east 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 DEG C under a load of 2.16 kgf in accordance with Japanese Industrial Standards (JIS) K7210.</p> |
