Abstract: A covering for a light-source made from or containing a polyolefin composition made from or containing:



(A) 50-80% by weight of a propylene polymer made from or containing from 0.1 to 40% by weight of units deriving from ethylene or an alpha-olefin of formula CH2═CHR1, where R1 is a linear or branched C2-C8 alkyl, based on the weight of (A);
(B) 15-35% by weight of an elastomeric component selected from the group consisting of:

(B1) ethylene copolymers with an alpha-olefin,
(B2) saturated or unsaturated styrene or alpha-methylstyrene block copolymers, and
(B3) combinations thereof;


(C) 5-30% by weight of glass fibers; and
(D) 0-5.0% by weight of a compatibilizer,
wherein the amounts of (A), (B), (C), and (D) are based on the total weight of (A)+(B)+(C)+(D).

Abstract: A method for the production of metal-plated articles, including the step of



depositing an electrically-conductive metallic layer on a surface of an article comprising a polymer composition comprising by weight:

a) 40-60% of a propylene homopolymer, or propylene copolymer containing up to 5% by weight of ethylene and/or another C4-C10 α-olefin, and having a melting temperature of 155° C. or higher and/or a fraction soluble in xylene at 25° C. of 10% by weight or less;
b) 10-20% of an ethylene-based elastoplastic copolymer, optionally, a copolymer of ethylene with C4-C10 α-olefin;
c) 2-6% of a styrene block copolymer;
d) optionally, up to 3% of a propylene homopolymer having a Melt Flow Rate (230° C./2.16 kg) of 500 g/10 min. or more;
e) 15-50% of a filler; and
f) optionally, up to 6% of a color pigment.
