Abstract

The invention relates to a polypropylene composition (C) comprising: (i) 62 to 85 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO1) with a melt flow rate MFR 2 (230 °C) measured according to ISO 1133 in the range of 6.0 to 50.0 g/10min; (ii) 10 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO2) with a melt flow rate MFR 2 (230 °C) measured according to ISO 1133 in the range of 0.1 to 5.5 g/10min; (iii) 5 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of an inorganic filler (F); wherein (a) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower amount [in mol%] of C 2 and/or C 4 to C 12 ±-olefin derived comonomer units than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); (b) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower the intrinsic viscosity (IV) than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); and (c) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2) has an intrinsic viscosity (IV) in the range of 6.0 to 15.0 dl/g.
