FIREPROOFING INSULATING SUBSTANCE FOR ELECTRIC CABLE

摘要

A fire-proofed material for an electric cable, said material including a matrix made of a copolymer of propylene and of ethylene, high-density polyethylene or thermoplastic polyester, a fire-proofing agent which is halogenated and is formed by a cyclic derivative of pentaerythritol, an aliphatic or cyclo-aliphatic derivative which is stable at the extrusion temperature of the matrix and decomposes at a higher temperature and a mineral compound of antimony which is able to react with the bromine of the fire-proofing agent during combustion.
