Flame retardant composition and insulated wires for use in electronic equipment

Abstract

This invention relates to a flame retardant composition comprising Component (A) being a thermoplastic copolyester elastomer comprising 20 to 80 wt. % of monomeric units derived from a dimerised fatty acid or a derivative thereof and further monomeric units derived of at least one dicarboxylic acid and at least one diol, wherein wt % is with respect to the total weight of the thermoplastic copolyester elastomer; and Component (B) being 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—R3—PR2(O)O]2-nMxm+ (formula II), and/or a polymer thereof, wherein —R1 and R2 are equal or different substituents chosen from the group consisting of hydrogen, linear, branched and cyclic C1-C6 aliphatic groups, and aromatic groups, —R3 is chosen from the group consisting of linear, branched and cyclic C1-C10 aliphatic groups and C6-C10 Caromatic 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; as well as an insulated wire for use in electronic equipment, comprising an electrically conductive core and an insulating layer and/or an insulating jacket comprising or consisting of the flame retardant composition.
