Abstract:
Composition having a melt flow rate MFR2 (230° C.) in the range of 10 to 50 g/10 min. said composition comprises two heterophasic polypropylenes comprising a propylene homopolymer matrix and an elastomeric copolymer, a plastomer and a mineral filler, wherein—said two heterophasic polypropylenes have different melt flow rates, —the first heterophasic polypropylene has a melt flow rate MFR2 (230° C.) in the range of 3.0 to 30.0 g/10 min and—the second heterophasic polypropylene has a xylene cold soluble (XCS) content in the range of 7.0 to 20.0 wt.-%.
