ABSTRACT OF THE DISCLOSURE The addition of 2-30 parts of zinc oxide to stabilized plasticized polyvinyl halide compositions results in reduced smoke generation under burning conditions. Optionally calcium carbonate or magnesium oxide is incorporated as a synergistic filler. Synthetic materials undergoing forced combustion emit smoke and toxic gases which are dangerous fire hazards because they impair escape, produce injury, limit survival and hamper fire fighting efforts. This is especially true for such applications as linings of aircraft, watercraft, motor vehicles, and house interiors, as well as for furniture and the like.
