Abstract

Tiger stripe modifier being a heterophasic polypropylene composition having a melt flow rate MFR 2 (230°C) in the range of 0.5 to 20 g/10min and comprises a propylene homopolymer and an elastomeric propylene copolymer, wherein said propylene homopolymer has a melt flow rate MFR 2 (230°C) in the range of above 10 to 300 g/10min; the xylene cold soluble fraction of the heterophasic polypropylene composition has an intrinsic viscosity in the range of more than 2.5 to below 11.0 dl/g; and the comonomer content of the xylene cold soluble fraction of the heterophasic polypropylene composition is in the range of 10.0 to 25.0 wt.-%; wherein further the heterophasic polypropylene composition fulfills the inequation (I) wherein C is the comonomer content of the xylene cold soluble (XCS) fraction of the heterophasic polypropylene composition (HECO1), and IV is the intrinsic viscosity of the xylene cold soluble (XCS) fraction of the heterophasic polypropylene composition (HECO1).
