Patent ID: 8076581

Claim:
An insulated wire for use in electronic equipment, comprising an electrical conductive core and an insulating layer and/or an insulating jacket consisting of a flame retardant polymer composition surrounding the electrically conductive core, wherein the flame retardant elastomeric composition, expressed as % wt relative to the weight of the total flame retardant elastomeric composition, consists essentially of: (A) 10 wt % to 70 wt % styrenic block copolymer, (B) 3 wt % to 35 wt % of 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, and (C) 10 wt % to 65 wt % copolyetherester elastomer; and optionally, (D) 0 wt. % to 15 wt. % PP and/or LLDPE, (E) 0 wt. % to 15 wt % of a flame retardant component consisting of a nitrogen containing flame retardant synergist and/or a phosphor/nitrogen containing flame retardant, (F) 0 wt. % to 5 wt. % of 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; and (G) 0 wt % to 10 wt % of additives, and wherein the insulated wire is a bipolar or tripolar wire consisting of two or three electrically conductive cores, two or three insulating layers each surrounding one of the electrically conductive cores, and optionally a jacket layer surrounding the electrically conductive cores and the insulating layers, wherein the insulating layers and/or the jacket layer consist of the flame retardant elastomeric composition.
