Thermally resistant crosslinked wire

Abstract

A thermally resistant crosslinked wire wherein a bromine-based flame retardant and a resin composition containing magnesium hydroxide are used. The thermally resistant crosslinked wire comprises a high-density polyethylene, low-density polyethylene, an ethylenic copolymer, a resin made of an ethylenic copolymer denatured by an unsaturated carboxylic an-hydroxide, a bromine-based flame retardant, and magnesium hydroxide. The wire is obtained by crosslinking the coating layer, with which the periphery of a conductor is coated. In the resin composition, the total blending amount of the bromine-based flame retardant and magnesium hydroxide with respect to 100 parts by mass of the resin is in a range of 30 to 55 parts by mass. The type-D durometer harness of the resin composition according to JIS K7215 is in a range of 56 to 64. The specific gravity obtained using the water displacement method according to JIS K7112 is in a range of 1.14 to 1.25.
