FIELD: chemistry.
SUBSTANCE: composition contains a random copolymer of propylene and ethylene (A), in which the ethylene content is 2-9 mol. %, the ethylene copolymer and α-olefin (B) produced by copolymerization of ethylene with one or more αolefins having 3-10 carbon atoms, a fibrous filler (C) having an average fibre length of 0.1 to 2 mm and an average fibre diameter of 1-25 microns, lubricant (D) and polypropylene modified with unsaturated carboxylic acids or their derivatives (E). The random copolymer of propylene and ethylene (A) has a melt flow rate (ASTM D1238, 230 °C, under load 2.16 kg) of 5 to 100 g/10 min, and a copolymer of ethylene and α-olefin (B) has a melt flow rate (ASTM D1238, 230 °C, under load 2.16 kg) of 0.1 to 80 g/10 min.
EFFECT: resistance to surface damage, excellent mechanical properties.
