[Also in Division C3] Articles made from halogen-containing plastics materials which liberate hydrogen chloride on burning contain a substance of a nature, and in sufficient amount, which liberates a volatile compound which combines with all the hydrogen chloride when burning occurs and which is incorporated in another material attached to the halogen-containing plastics. There may also be present a compound which facilitates the liberation of the volatile compound e.g. a metal oxide. In examples are used dicyanogen diamide, urea, ammonium sulphate, sec. ammonium phosphate and combinations thereof in amounts of 90-120 phr together with magnesium, zinc or titanium oxide in butyl rubber sheeting laminated to P.V.C. sheet.
