PURPOSE:To provide titled composition capable of forming heat-insulating layer by foam generation and carbonization on coming into contact with flame, made up of specific ingredient(s) and resin component comprising polyvinyl chloride and ethylene-vinyl acetate copolymer. CONSTITUTION:The objective resin composition made up of (A) a resin component comprising (i) polyvinyl chloride and (ii) ethylene-vinyl acetate copolymer (pref. with a vinyl acetate content >=15wt% and melt index <=15), (B) zinc compound (e.g., zinc carbonate, zinc borate, zinc phosphate, zinc pyromellitate), (C) acrylic and/or methacrylic acid compouned(s) (e.g. methyl methacrylate), and (D) one or more sorts of compounds selected from oxides, hydroxides and carbonates of such metals as antimony, molybdenum, silicon, aluminum, magnesium, and calcium. |
