Zusammenfassung: | The present invention relates to a flame retardant polymer composition comprising(A) 2.0 to 15.0 wt% of a copolymer of ethylene comprising units selected from the group consisting of methyl acrylate, methyl methacrylate or mixtures thereof;(B) 0 to 4.0 wt% of a polyethylene and/or polypropylene containing units originating from maleic acid anhydride;(C) 0.1 to 3.0 wt% of a silicon fluid and/or silicone gum;(D) 40.0 to 55.0 wt% of a magnesium hydroxide;(E) 2.0 to 15.0 wt% of a copolymer of ethylene and alpha olefin comonomer units having from 4 to 10 carbon atoms, which has a density of from 860 to 910 kg/m3, determined according to ISO 1183;(F) 18.0 to 35.0 wt% of a copolymer of ethylene and alpha olefin comonomer units having from 4 to 10 carbon atoms, which has a density of from 920 to 960 kg/m3, determined according to ISO 1183, and a melt flow rate MFRs of from 0.05 to 2.50 g/10 min, determined according to ISO 1133 at a temperature of 190°C and a load of 5.0 kg; and(G) 0 to 8.0 wt% of carbon black, wherein all weight percentages are based on the total weight of the flame retardant polymer composition;an article, such as a wire or cable, comprising said flame retardant polymer composition; and the use of said flame retardant polymer composition for the production of an article, such as a wire or cable. |
