Abstract: A polypropylene resin composition for molding material, which is excellent in an appearance of weld line and an appearance of tiger stripe and is used for automobile exterior parts and an automobile exterior part comprising the same, are provided.

Abstract: Provided are a polypropylene resin composition that excels not only in fluidity but also in balance between rigidity and impact resistance, and that can, when being molded into an automotive injection molded article, provide an automotive injection molded article excelling in weld appearance and flow mark appearance, and an automotive injection molded article made thereof. There is provided a polypropylene resin composition comprising 50 to 65 wt % of propylene-ethylene block copolymer (A-1) containing crystalline propylene homopolymer segment and propylene-ethylene random copolymer segment of 4.0 to 5.5 dl/g in intrinsic viscosity; 1 to 10 wt % of ethylene-?-olefin copolymer rubber (B) of 0.05 to 1 g/10 min in melt flow rate; 8 to 18 wt % of ethylene-?-olefin copolymer rubber (C) of 2 to 20 g/10 min in melt flow rate; and 18 to 25 wt % of inorganic filler (D), the sum of the rubbers (B) and (C) being 17 to 25 wt %. Further, an automotive injection molded article of the composition is provided.

Abstract: A polypropylene composite that includes 50 to 75 weight percent of polypropylene resin based on the weight of the polypropylene composite. The polypropylene resin has a melt flow rate of from 20 to 300 at 230° centigrade under a 2.16 kilogram load. The polypropylene composite also includes from 5 to 15 weight percent based on the weight of the polypropylene composite of ethylene-alpha-olefin diene copolymer rubber. The ethylene-alpha-olefin diene copolymer rubber has a melt flow rate of less than 0.4 at 230° centigrade under a 2.16 kilogram load. Also included is from 5 to 15 weight percent of an ethylene-alpha-octene copolymer rubber having a melt flow rate of from 0.5 to 20 at 230° centigrade under a 2.16 kilogram load Also a ratio of ethylene-alpha-olefin diene copolymer rubber divided by a total content of ethylene-alpha-olefin diene copolymer rubber and ethylene-alpha-octene copolymer rubber is 0.35-0.45.
