Patent ID: 8536449

Claim:
An insulated wire for use in electronic equipment, consisting of an electrically conductive core and an insulating layer and/or an insulating jacket surrounding the electrically conductive core to impart to the insulated wire a vertical flame retardancy which complies with UL Standard UL1581 VW-1, wherein the insulating layer and/or the insulating jacket consist of a flame retardant thermoplastic composition surrounding the electrically conductive core, and wherein the flame retardant thermoplastic composition consists of: (A) a thermoplastic polymer comprising a copolyester elastomer, (B) a metal salt of a phosphinic acid of the formula [R 1 R 2 P(O)O] m M m + (formula I) and/or a diphosphinic acid of the formula [O(O)PR 1 —R 3 —PR 2 (O)O] 2 n M x m + (formula II), and /or a polymer thereof, wherein R 1 and R 2 are equal or different substituents chosen from the group consisting of hydrogen, linear, branched and cyclic C1-C6 aliphatic groups, and aromatic groups, R 3 is 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, (C) a flame retardant component consisting of a nitrogen containing flame retardant synergist and/or a phosphor/nitrogen containing flame retardant, and (D) an inorganic compound chosen from the group consisting of basic and amphoteric oxides, hydroxides, carbonates, silicates, borates, stannates, mixed oxide-hydroxides, oxide-hydroxide-carbonates, hydroxide-silicates and hydroxide-borates, and mixtures thereof.
