Title:
COMPOSITION FOR ELECTRIC WIRE PROTECTIVE MATERIALS, ELECTRIC WIRE PROTECTIVE MATERIAL AND WIRING HARNESS
Document Type and Number:
WIPO Patent Application WO/2015/125574
Kind Code:
A1
Abstract:
Provided are: a composition for electric wire protective materials, which is capable of preventing deposition and adhesion of a flame retardant on a die orifice during extrusion molding of a flame-retardant polyolefin resin composition, and which provides a molded article having good heat resistance and flame retardancy, while having excellent productivity; an electric wire protective material; and a wiring harness.
This composition for electric wire protective materials is configured of a polypropylene resin composition which contains a polypropylene resin, and a bromine-based flame retardant and antimony trioxide that serve as a flame retardancy-imparting agent, said bromine-based flame retardant having a melting point of 110°C or more, and which does not contain any metal oxide other than antimony trioxide. This electric wire protective material is obtained by molding the composition into a predetermined shape that is capable of protecting an electric wire. This wiring harness is configured by covering the circumference of an electric wire bundle, which is obtained by bundling a plurality of insulated wires together, with this electric wire protective material.
