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 invention relates a process for the preparation of a bonded structure (4) comprising at least a first plastic part (1) having a first bonding surface (1a), said process comprising the step of a) treating at least part of a first bonding surface of said first plastic part with a flame of a propane-comprising gas, said propane-comprising gas being propane or a mixture comprising at least 50 wt. % of propane based on the weight of the propane-comprising gas with one or more gases selected from the group consisting of methane, ethane, butane, pentane, and hexane, wherein, during treatment with a flame of the propane-comprising gas, a flame is produced by burning a mixture of air and the propane-comprising gas, wherein the gas-to-air ratio is chosen such that the propane gas to oxygen volume ratio is equal to or less than 1:5.01, for example less than 1:5.00 and preferably at least 3.50 to obtain a first plastic part having a flame-treated first bonding surface.
