ABSTRACT:
The invention relates to an insulated wire for use in electronic equipment, comprising an electrically conductive core and an insulating layer and/or an insulating jacket consisting of a flame retardant elastomeric composition surrounding the electrically conductive core, wherein the flame retardant elastomeric composition comprises a elastomeric polymer selected from the group consisting of styrenic block copolymers, thermoplastic elastomers and combinations thereof; and a metal salt of a phosphinic acid of the formula [R1R2P(O)O]−mMm+(formula I) and/or a diphosphinic acid of the formula [O(O)PR1—R—PR2(O)O]2−nMxm+(formula II), and/or a polymer thereof, wherein R1and R2are equal or different substituents chosen from the group consisting of hydrogen, linear, branched and cyclic C1-C6 aliphatic groups, and aromatic groups, R3is chosen from the group consisting of linear, branched and cyclic C1-C10 aliphatic groups and C6-C10 aromatic and aliphatic-aromatic groups, M is a metal chosen from the group consisting of Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, and K, and m, n and x are equal or different integers in the range of 1-4.
