PROBLEM TO BE SOLVED: To provide a composition for wire coating material capable of reducing a filler as a flame retardant as much as possible without using an electron ray crosslinking, high in heat resistance, high in gel fraction, having flexibility and good in workability of a wire harness and the like, an insulation wire and a wire harness.SOLUTION: A wire coating material is composed of a composition containing (A) silane-grafted polyolefin in which a silane coupling agent is grafted to polyolefin having density of 0.855 to 0.885 g/cm, (B) unmodified polyolefin having density of 0.890 to 0.955 g/cm, (C) modified polyolefin modified with one or more functional group selected from a carboxylic acid group, an acid anhydride group, an amino group, an acryl group, a methacryl group and an epoxy group, (D) a bromine-based flame retardant and antimony trioxide, (E) a crosslinking catalyst batch, (F) zinc oxide and imidazole compound/or zinc sulfide, (G) an antioxidant, (H) a metal inactivation agent and (I) a lubricant.SELECTED DRAWING: None |
