Composition for wire protective member, wire protective member, and wiring harness

Abstract

A composition for a wire protective member with heat resistance, flame retardancy, and resistance against both a calcium chloride and a braided wire; a wire protective member and a wire harness using the composition. The composition for a wire protective member is produced by including a polypropylene having a propylene monomer constituting 50 to 95 percent by mass of monomers forming a polymer, a melt flow rate of 0.5 to 5 g/10 min, and a melting point of 150 degrees C. or more; a bromine-based flame retardant and an antimony trioxide as a flame retarder; a phenol-based antioxidant as a heat resistance life improving agent; and a metal deactivator, wherein the propylene has a tensile strength of 20 to 35 MPa and a Charpy impact strength of 10 kJ/m2 or more at 23 degrees C.
