retardant polymer composition Flame

retardant polymer composition flame, comprising: (A) an ethylene copolymer prepared under high pressure comprising selected from the group comprising acrylic acids, methacrylic acids, acrylates, methacrylates, acetates and vinyl ester polar groups, in an amount between 15 and 25% by weight of the total polymer composition; (B) an ethylene copolymer prepared with a single site catalyst comprising comonomer units derived from a-olefin C4 to C12, having a density between 0.860 and 0.910 g / cm3 measured according to ISO 1183, in an amount between 3 to 20% by weight of the total polymer composition; (C) a free halogen mineral filler comprising huntite and / or hydromagnesite in an amount between 45 and 70% by weight of the total polymer composition; (D) a homopolymer or copolymer of ethylene maleic anhydride modified in an amount between 1 and 10% by weight of the total polymer composition; (E) an ethylene (E) having a density between 0.912 and 0.940 g / cm3 measured according to ISO 1183 in an amount between 1 and 7% by weight of the total polymer composition.
