Abstract
A flame retardant polymer composition comprising (A) an ethylene copolymer comprising polar comonomer units, (B) a silicone-group containing compound, (C) an inorganic filler material, and (D) an ethylene homopolymer or a copolymer of ethylene with one or more other alpha-olefin comonomer units, wherein the polymer composition has a melting enthalpy of at least 78 J/g, an article, in particular a wire or cable, comprising said composition and the use of an ethylene homo- or copolymer in a flame retardant layer of a wire or cable for improving the mechanical properties of the wire or cable.
