COMPOSITE HARD POLYPROPYLENE COMPOSITION, SUITABLE FOR UNIMENSIONAL APPLICATION OF PAINT COATING

摘要

The present invention relates to a polypropylene composition (C), a product containing a polypropylene composition (C), and the use of a polypropylene composition (C). The technical result of the invention is the reduction of defects in the paintedability of the molded product. The essence of the invention is that the polypropylene composition (C) contains: (a) from 20.0 to 60.0 wt.% Of the total weight of the composition of a heterophasic propylene copolymer (HPP) with a MFR melt flow rate (230 ° C), measured according to ISO 1133, in the range from 10.0 to 40.0 g / min, containing: (a1) a polypropylene matrix (M) and (a2) an elastomeric propylene copolymer (E1); (b) from 5.0 to 70.0% by weight of the total weight of the polypropylene homopolymer composition (PP-H1) and (c) from 20.0 to 40.0% by weight of the total weight of the composition of mineral filler (F), selected from the group consisting of talc, wollastonite, kaolin and mica, where the polypropylene composition (C) has a MFR melt flow rate (230 ° C), measured according to ISO 1133, ranging from 10.0 to 25.0 g / min.
