Abstract: The present invention is directed to a polypropylene composition (C) comprising a heterophasic propylene copolymer (HECO1) having an intrinsic viscosity (IV) of the xylene soluble fraction (XCS) above 3.5 dl/g, an inorganic filler (F) and a nucleating agent (NU) being a dicarboxylic acid and/or a salt thereof. Further, the present invention is directed to the use of said polypropylene composition (C) for the production of a foamed article as well as a foamed article comprising said polypropylene composition (C). The present invention is also directed to the use of a nucleating agent (NU) being dicarboxylic acid and/or a salt thereof for the reduction of tigerskin of a polypropylene composition.
