Abstract
Heterophasic propylene copolymer comprising —a matrix (M) being a polypropylene, said polypropylene comprises at least three polypropylene fractions, the three polypropylene fractions differ from each other by the melt flow rate MFR(230° C.) and at least one of the three polypropylene fractions has a melt flow rate MFR(230° C.) in the range of 1.0 to 15.0 g/10 min, and —an elastomeric propylene copolymer dispersed in said matrix, wherein —the heterophasic propylene copolymer has a melt flow rate MFR(230° C.) of equal or more than 20.0 g/10 min, and —the amorphous phase of the xylene cold soluble fraction of the heterophasic propylene copolymer has an intrinsic viscosity of equal or higher than 2.0 dl/g.
