Flame-retardant resin composition

Abstract

Abstract PURPOSE:To provide the titled compsn. which is non-tacky and suitable for use as a covering material for electric cables and wires, by blending aluminum hydroxide and amorphous silica or carbon black with a resin compsn. consisting mainly of an ethylene/vinyl acetate copolymer. CONSTITUTION:As a base plastic, an ethylene/vinyl acetate copolymer having a vinyl acetate content of 40wt% or higher is used. Two kinds of ethylene/vinyl acetate copolymers are mixed together in such a proportion as to give a vinyl acetate content of 40wt%. The mixture may be used as a base plastic. Alternatively, a mixture obtd. by replacing part of said ethylene/vinyl acetate copolymer or copolymers with a polyolefin such as polyethylene may be used as a base plastic. 120-250pts.wt. aluminum hydroxide and 5-70pts.wt. amorphous silica, carbon black or mixture thereof are blended with 100pts.wt. base plastic to obtain the desired flame-retardant resin compsn.
