Abstract

PURPOSE:A composition with high oil resistance that is obtained by adding melamine phosphate and/or melamine borate, which are coated with a lubricant on their surfaces, to a mixture of a vinyl chloride resin and a macromolecular compound, thus showing insulation action by forming carbonized foam layers to fire flames. CONSTITUTION:Melamine phosphate and/or melamine borate whose surfaces are treated with a lubricant are added to a mixture of a vinyl chloride resin and a macromolecular compound compatible with the same. It is preferred that a molybdenum compound selected from metal molybdenate salts is added additionally. As the macromolecular compound, is used an ethylene-vinyl acetate copolymer or the like. The melamine compounds are added to the vinyl chloride resin by 2-40pts.wt. per 100pts.wt. of the resin. EFFECT:The resultant composition shows good resistance to thermal deformation.
