PURPOSE:A composition, obtained by incorporating a propylene based highly crystalline polymer with ethylene based polymer, etc., in specific amounts, and capable of giving molded articles having improved combined characteristics of low-temperature impact resistance, rigidity and surface scuff resistance. CONSTITUTION:A polyolefin composition obtained by incorporating (A) 40-60 pts.wt. propylene based highly crystalline polymer having >=0.90g/cm<3> density, 0.1-100g/10min melt flow rate (230 deg.C), etc. with (B) 5-10pts.wt. ethylene based high-density polymer having >=0.94g/cm<3> density and 0.01-20g/10min melt flow rate (190 deg.C), (C) 8-15pts.wt. low crystalline 1-olefin copolymer having having 0.05-6g/10min melt flow rate (190 deg.C) and 0.1-10g/10min melt flow rate (230 deg.C), (D) 21-45pts.wt. inorganic filler, preferably 20-35pts.wt. fine powdery talc and 1-10pts.wt. fine powdery calcium carbonate and (E) 0.1-5pts.wt. higher fatty acid amide (derivative thereof) to give 100pts.wt. total amount. |
