Abstract
A composition for a wire coating material containing a silane-crosslinked polyolefin which is excellent in flame-retardancy, fusion resistance, and heat-deformation resistance, and an insulated wire and a wiring harness coating the composition. A composition for a wire coating material contains (A) a silane-grafted polyolefin which is a polyolefin graft-modified with a silane coupling agent, (B) an unmodified polyolefin, (C) a modified polyolefin having one or more functional groups selected from the group consisting of a carboxy group, an ester group, an acid anhydride group, an amino group, and an epoxy group, (D) a flame retardant, and (E) a crosslinking catalyst. The polyolefin of (A) the silane-grafted polyolefin has a density of 0.855 to 0.890 g/cmin an ungrafted state and has a melting point of 80° C. or higher, and the unmodified polyolefin has a density of 0.855 to 0.950 g/cm.
