である。Among these solutions, it has a heat resistance of 120 to 160 °C,
Moreover, as a crosslinked polyolefin composition with excellent flame retardancy without deteriorating electrical properties, antimony oxide is combined with a halogen-containing flame retardant such as decabromo biphenyl ether for polyethylene or a copolymer mainly composed of ethylene. Added systems are known. However, the reality is that these known techniques cannot prevent the dripping phenomenon (a phenomenon in which burning materials melt and fall during combustion) in the vertical combustion test required for electrical wires used in electronic equipment wiring. .

を完全に解消し得ることを見出し本発明を完成した。The inventor of the present invention has conducted various experiments in order to solve this problem and provide an electric wire that is electrically superior and satisfies the heat resistance and flame resistance required by the market, and as a result, has developed a wire that is mainly made of polyethylene or ethylene. Decabromo biphenyl ether and tetrabromo bisphenol A are added to the base polymer, which is obtained by adding 5 to 50 parts by weight, preferably 10 to 15 parts by weight, of a silicone ethylene propylene copolymer to 100 parts by weight of the copolymer.
, perchlorocyclopentadecane, paraffin monochloride,
It has been found that the above-mentioned drawbacks can be completely eliminated by adding a flame retardant in which antimony trioxide is combined with a halogen-containing flame retardant such as 22-di(4-bromoethoxy-3.5-dibromophenyl)propane, followed by crosslinking. Heading The invention has been completed.
