    Abstract: The invention is directed to a polypropylene composition, to a three-dimensional article comprising said polypropylene composition, and to the use of said composition for automotive articles. The polypropylene composition of the invention comprises: —40-90% by total weight of the composition of a polymer blend comprising polypropylene having a melt flow index as measured according to ISO 1133 at 230° C. and 2.16 kg of 2.0-100 g/10 min; —5-25% by total weight of the composition of one or more plastomers; —0.5-25% by total weight of the composition of mineral filler selected from the group consisting of phyllosilicates, mica or wollastonite; and —0.2-4% by total weight of the composition of glass fibers having an average fiber diameter in the range of 5-30 μm.

    Abstract: The present invention relates to an exterior or semi-exterior automotive part prepared from a thermoplastic composition comprising: from 48-95 wt. % heterophasic propylene copolymer; wherein said heterophasic propylene copolymer consists of i) a propylene-based matrix, and ii) a dispersed ethylene-α-olefin copolymer comprising ethylene and at least one C3 to C10 α-olefin; from 0-20 wt. % ethylene-α-olefin elastomer comprising ethylene and at least one C3 to C10 α-olefin; from 1 up to 30 wt. % high aspect ratio (HAR) talc as a filler; from 0 to 5 wt. % of another talc; from 0.05-1 wt. % phenolic antioxidant additive; from 0.05-1 wt. % amphiphilic protective additive comprising a hydrophilic part and a hydrophobic part; and from 0-3 wt. % additional additives. It moreover relates to a method of producing these and to the use of such a composition for the manufacture of an exterior or semi-exterior part in automotive applications.
