RESIN COMPOSITE FOR CABLE INSULATING COVERING

摘要

PURPOSE: To eliminate chlorine gas dispersion to prevent discoloration of a conductor in a wire/cable insulating covering resin composite composed mainly of chlorinated polyethylene. ;CONSTITUTION: The composite is composed of mixture of chlorinated polyethylene with ethylene vinyl acetate(EVA) or ethylene ethylacrylate(EEA), and 10-150PHR of magnesium hydroxide (Mg(OH)₂) is added to the mixture. The magnesium hydroxide adsorbs decomposed chlorine gas. Accordingly, erosion of a conductor (plating) due to the chlorine gas is eliminated and discoloration is not caused. Blending of the EVA or EEA enhances flexibility.;COPYRIGHT: (C)1993,JPO&Japio
