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 polymer blend obtained by melt blending a mixture made from or containing:



(A) 60% to 98.8% by weight of a polyolefin;
(B) 0.1% to 30% by weight of a compatibilizer;
(C) 0.05% to 20% by weight of an amino resin; and
(D) 0% to 5% by weight of an additive,
wherein the amounts of (A), (B), (C), and (D) are based on the total weight of (A)+(B)+(C)+(D), the total weight being 100%.
