Abstract:
The present invention relates to a polymer composition comprising a polyolefin base resin comprising (A) a propylene homopolymer with a MWD of 1.5 to 5.0, and (B) an ethylene copolymer with one or more comonomers selected from alphaolefins with 4 to 12 carbon atoms, having a density of not greater than 920 kg/m3 wherein the polyolefin base resin has a weight ratio of propylene homopolymer (A) to ethylene copolymer (B) from 95:5 to 60:40, the use of such a polymer composition for the manufacture of an injection molded article, an article produced from such a polymer composition, an article with a grained surface structure produced from such a polymer composition showing having a scratch resistance, determined as the difference of the luminance ΔL at a load of 10 N, of not more than 1 and a gloss at an angle of 60° of not more than 2.8%, and the use of a polymer composition for the production of such an article.
