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

Composition having a melt flow rate MFR(230&#xb0; C.) measured according to ISO 1133 in the range of 15 to 30 g/10 min, said composition comprises a heterophasic propylene copolymer (H-PP1), a high melt flow polypropylene (HMF-PP), a styrenic block copolymer (SBC) and a mineral filler (F), wherein (a) the heterophasic propylene copolymer (H-PP1) has a xylene cold soluble (XCS) content measured according to ISO 6427 in the range of 22.0 to 50.0 wt.-% and comprises (a1) a polypropylene matrix (M1) and (a2) an elastomeric copolymer (E1) comprising units derived from propylene and ethylene and/or Cto C&#x3b1;-olefin, (b) the melt flow rate MFR(230&#xb0; C.) measured according to ISO 1133 of the high melt flow polypropylene (HMF-PP) is higher than the melt flow rate MFR(230&#xb0; C.) measured according to ISO 1133 of the heterophasic propylene copolymer (H-PP1), and (c) the high melt flow polypropylene (HMF-PP) has melt flow rate MFR(230&#xb0; C.) measured according to ISO 1133 of at least 40.0 g/10 min.

Automotive interior compound

Exterior automotive article comprising a composition comprising a polypropylene, an elastomeric copolymer, and a mineral filler, wherein said polypropylene (PP) has a comonomer content of equal or below 1.0 wt.-%, the comonomers are ethylene and/or at least one Cto Ca-olefin, and &#x3c;2,1&#x3e; erythro regiodefects of equal or more than 0.4 mol.-%, said elastomeric copolymer (EC) comprises units derived from ethylene and at least one Cto Ca-olefin, said composition (C) has a melt flow rate MFR(230&#xb0; C.) in the range of 5 to 80 g/10 min.

Exterior automotive article with reduced paintability failure

Use of an inosilicate in a polymer composition to accomplish a headspace emission of all volatiles together of said polymer composition of equal or below 120 &#x3bc;gC/g.

Polypropylene mineral compound with reduced volatiles

Composition comprising polypropylene and (a) at least one phenolic antioxidant (A) (b) at least one hindered amine light stabilizer (B) (c) at least one slip agent (C) being a fatty acid amide, (d) a bisphenol A epoxy resin with an average molecular weight (Mw) below 2000 g/mol (D), and (e) talc (E).
