Document Type and Number:
Japanese Patent JP6947857
Kind Code:
B2
Abstract:
To provide an electric wire excellent in flame resistance and mechanical characteristics.SOLUTION: An electric wire 10 has a conductor 1, and an insulating layer 2 coating the periphery of the conductor 1. The insulating layer 2 is formed of a base polymer and a flame-retardant resin composition containing a flame retardant, the base polymer contains an ethylene-vinyl acetate copolymer and a modified polymer, and the flame-retardant agent contains a metal hydroxide, a nitrogen-based flame-retardant agent and a zinc-based compound. The modified-polymer is polyolefin modified with an unsaturated carboxylic acid or its derivative, and the ethylene-vinyl acetate copolymer contains a first ethylene-vinyl acetate copolymer having a vinyl acetate content of 60 mass% or more and a second ethylene-vinyl acetate copolymer having a vinyl acetate content of less than 60 mass%.SELECTED DRAWING: Figure 1
