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 filled polyolefin composition made from or containing a blend of a 30-70 wt. % of a first heterophasic polypropylene (HECO1) and 70-30 wt. % of a second heterophasic polypropylene (HECO2), wherein the heterophasic copolymers differ in MFR and type of comonomers, in combination with glass fibers and optionally a compatibilizer.
