Abstract
The invention is directed to a polypropylene composition, to a three-dimensional article comprising said polypropylene composition, and to the use of said polypropylene composition. The polypropylene composition of the invention comprises a) a multimodal polypropylene homopolymer comprising at least the following fractions i) 10-30% by total weight of the polypropylene composition of a fraction with a melt flow index of 5-45 g/10 min; ii) 10-30% by total weight of the polypropylene composition of a fraction with a melt flow index of 50-200 g/10 min; and iii) 3-10% by total weight of the polypropylene composition of a fraction with a melt flow index of 250-900 g/10 min; wherein the melt flow index is as measured according to ISO 1133 using a 2.16 kg weight and at a temperature of 230° C.; b) 1-8% by total weight of the polypropylene composition of a first C/Cphase having an intrinsic viscosity at 135° C. of 1.5-2.5 dl/g, of which the ethylene content in the xylene cold soluble fraction is 45-65% by total weight of the xylene cold soluble fraction; c) 1-8% by total weight of the polypropylene composition of a second C/Cphase having an intrinsic viscosity at 135° C. of 2.6-4.0 dl/g, of which the ethylene content in the xylene cold soluble fraction is 45-65% by total weight of the xylene cold soluble fraction; d) 10-25% by total weight of the polypropylene composition of a C/Cphase having an intrinsic viscosity at 135° C. of 1.2-2.1 dl/g and a density of 0.85-0.89 g/cm3; and e) 10-30% by total weight of the polypropylene composition of a mineral filler.
