Polypropylene-based resin composition and injection molded article comprising the same

摘要

Disclosed are a polypropylene-based resin composition comprising (i) a resin composition comprising specific amounts of a propylene-ethylene block copolymer (A-1), a copolymer rubber of ethylene and alpha-olefin having from 3 to 20 carbon atoms (B), the copolymer rubber having a density of from 0.85 to 0.885 g/cm<3>, an inorganic filler (C), and optionally a propylene homopolymer (A-2), and (ii) a small amount of an fatty acid amide (D). The resin composition is excellent in balance between rigidity and impact resistance and in scratch resistance.
