Abstract: The present invention relates to a polypropylene composition, an injection molded article comprising the polypropylene composition, a foamed article comprising the polypropylene composition as well as the use of a polypropylene homopolymer (H-PP1) for reducing the 5stiffness reduction factor of a foamed injection molded article by at least 40 as determined by the difference of the flexural modulus measured according to ISO 178 of the non-foamed and foamed injection molded article and compared to an article comprising the same amount of a polypropylene which has been polymerized in the presence of a Ziegler-Natta catalyst.

Abstract: The present invention relates to novel polypropylene compositions suitable for automotive applications, having a good balance of mechanical properties and especially low gloss. The inventive compositions are characterised by at least two heterophasic propylene copolymers (HECOs), where at least one of the HECOs is characterised by a rather high molecular weight rubber, an ethylene-a-olefin elastomer (EOE) having a rather low melt flow rate MFR2 (190° C.) and a specific ratio between the MFR of the ethylene-a-olefin elastomer (EOE) and of at least one of the heterophasic propylene copolymers (HECOs).
