    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.

    Abstract: The present invention relates to an automotive part (such as an exterior automotive part, a semi-exterior automotive part or an interior automotive part) prepared from a thermoplastic composition comprising: from 48-95 wt. % based on the weight of the composition of a heterophasic propylene copolymer; wherein said heterophasic propylene copolymer consists of i) a propylene-based matrix consisting of a propylene homopolymer and/or a propylene-α-olefin copolymer, said propylene α-olefin copolymer consisting of at least 70 wt. %, and ii) a dispersed ethylene-α-olefin copolymer comprising ethylene and at least one C3 to C10 α-olefin; from 0-20 wt. %, preferably from 1-20 wt. % ethylene-α-olefin elastomer comprising ethylene and a C3 to C10 α-olefin; from 1-30 wt. % high aspect ratio; from 0.05-2 wt. % antioxidant additive selected from the group consisting of i) a tocopherol or a tocotrienol; or ii) a hydroxylamine from 0-3 wt. % an additional additive.
