GLASS FIBER REINFORCED POLYPROPYLENE COMPOSITION

Abstract: the invention relates to a fiber reinforced composition (c), wherein the fiber reinforced composition (c) has a melt flow rate mfr(230� c., 2.16 kg) determined according to iso 1133 in the range of 10.0 to 100.0 g/10 min, wherein the fiber reinforced composition (c) comprises a) 20.0 to 89.9 wt.-% of a propylene random copolymer (p), wherein the propylene random copolymer (p) is a copolymer of propylene and at least one comonomer selected from c4 to c12 �-olefins, wherein the propylene random copolymer (p) has an amount of 1,2 erythro regio-defects of 0.4 to 1.2 mol-%, b) 5.0 to 45.0 wt.-% of glass fibers (gf), c) 0.1 to 5.0 wt.-% of an adhesion promoter (ap), and d) 5.0 to 50.0 wt.-% of a heterophasic polypropylene copolymer (heco), based on the overall weight of the fiber reinforced composition (c). furthermore, the invention relates to articles comprising such fiber reinforced composition (c).
