This thesis investigated the effectiveness of Zinc Hydroxy Stannate (ZnSn (OH)6), Zinc Stannate (ZnSnO3) as fire retardants in plasticized polyvinyl chloride. The fire retardancy of the additives are studied by measuring the LOI value, evaluation the burning behavior in horizontal position, analysis for evolved toxic gas by pyrolysis gas chromatography technique and observe the mechanical properties changed of plasticized polyvinyl chloride film. It was found that zinc hydroxy stannate and zinc stannate had small effect on mechanical properties of plasticized polyvinyl chloride film and can be used as industrial fire retardants that show similar effectiveness as antimony trioxide in low plasticizer content polyvinyl chloride film and show less effectiveness than antimony trioxide in high plasticizer content polyvinyl chloride film and offer the advantages over antimony trioxide that they were non-toxic additives and can reduce the toxic benzene evolved from burning of the polymer.
