主权项

1: Polypropylene composition (C), the polypropylene composition (C) comprising:
(a) 40.0 to 80.0 wt. %, based on the total weight of the composition, of a propylene copolymer (R-PP) having
(a1) a comonomer content in the range of 1.5 to 8.0 wt. %, and(a2) a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 5.0 to 100.0 g/10 min, and (b) 20.0 to 40.0 wt. %, based on the total weight of the composition, of a mineral filler (F) being selected from the group consisting of talcum, wollastonite, caolin and mica, wherein the polypropylene composition (C) has a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 5.0 to 45.0 g/10 min.
