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).

Claim (Index 1):
Polypropylene composition (PPC) having a melt flow rate MFR 2  (230\u00b0 C.) measured according to ISO 1133 of 9.0 g/10 min, the composition comprising:\n a) at least two heterophasic propylene copolymers (HECOs), wherein the at least two heterophasic propylene copolymers (HECOs) are contained in a total amount of at least 50 wt %, based on the total weight of the composition, \n b) an ethylene-\u03b1-olefin elastomer (EOE) having a melt flow rate MFR 2  (190\u00b0 C.) measured according to ISO 1133 of <0.5 g/10 min, and \n c) wherein the ratio of the MFR 2  of at least one of the at least two heterophasic propylene copolymers (HECOs) to the MFR 2  of the ethylene-\u03b1-olefin elastomer (EOE) [MFR 2 (HECO)/MFR 2 (EOP)] is in the range of 2/1 to 100/1, and \n d) wherein the intrinsic viscosity (IV) measured according to ISO 1628-1 (decalin) of the xylene cold soluble (XCS) fraction of at least one of the at least two heterophasic propylene copolymers (HECOs) is 2.5 dl/g.
