Polypropylene resin composition for nozzle shaped objects like motor vehicle interior or external components and cabinet of electrical devices, has polypropylene resin, ethylene-alpha-olefin-copolymer rubber

摘要

The polypropylene resin composition has 50-94 wt.% of a polypropylene resin, 1-25 wt.% of an ethylene-alpha -olefin-copolymer rubber, and another ethylene-alpha -olefin-copolymer rubber. Third ethylene-alpha -olefin-copolymer rubber, and 5-25 wt.% of an inorganic filler are also provided. The former polypropylene resin is a crystalline propylene ethylene block copolymer or a polymer mixture, which comprises the block copolymer and a crystalline propylene homo polymer. The block copolymer is a crystalline statistic propylene-ethylene-copolymer.
