  • Publication number: 20090082509
    Abstract: A propylene polymer composition having a high impact strength and a high stiffness for the manufacture of parts having an excellent surface quality comprising A) 70 to 98 wt.-% of a heterophasic propylene copolymer with ethylene or an alpha-olefin with 4 to 12 carbon atoms, the propylene copolymer, which contains more than 60 wt.-% propylene, having a melt flow rate (MFR2) of 0.5 to 50 g/10 min and a ratio between elastomer molecular weight and total molecular weight expressed as Mw/Mw(XCS) of more than 0.8, Mw being the weight average molecular weight of the propylene copolymer and Mw(XCS) being the weight average molecular weight of the propylene copolymer which is soluble in xylene at +23° C., and the propylene copolymer further containing a portion of 5 to 35 wt.-% soluble in xylene at +23° C. (XCS content), B) 2 to 30 wt.-% of a mineral filler, C) 0.0001 to 1.0 wt.
