摘要： 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. Also included is from 20 to 25 weight percent based on the weight of the polypropylene composite of organic filler. Further included is from 0.1 to 5 weight percent based on the weight of the polypropylene composite of a grafted polypropylene and from 0.1 to 0.6 weight percent based on the weight of the polypropylene composite of a surface treatment material. The surface treatment material remains dispersed in the polypropylene composite preventing blooming of the surface treatment material when exposed to the environment.
