The invention is directed at a polypropylene composition comprising a heterophasic propylene copolymer, a plastomer and an inorganic filler. Furthermore, the invention is directed at an article comprising the polypropylene composition and the use of the polypropylene composition to improve the adhesion performance.

Polymer composition with improved paint adhesion

Thermoplastic polyolefin compounds for the production of injection molded, paintable and flame pre-treatable articles comprising A) 50 wt % to 90 wt % of a propylene homo- or copolymer matrix phase (M) and B) 10 wt % to 50 wt % of a first elastomer comprising an ethylene-C-C-alpha olefin copolymer rubber C) 0 wt % to 20 wt %, based on the total weight of A and B, of a second elastomer, component B) and C) forming a disperse phase (E) and D) &#x3e;30 wt % up to 60 wt %, based on the total weight of components A, B and C, of an inorganic filler, if the intrinsic viscosity of the disperse phase (E) is &#x3c;2.2 dl/g according to ISO 1628 (with decalin as solvent) or 0 wt % to &#x3c;30 wt % based on the total weight of components A, B and C, of an inorganic filler, if the intrinsic viscosity of the disperse phase (E) is &#x2267;2.2 dl/g according to ISO 1628 (with decalin as solvent).
