摘要:
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 characterized by at least two heterophasic propylene copolymers (HECOs), where at least one of the HECOs is characterized 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).
