ABSTRACT:
Smoke retardant compositions comprise a polyvinyl halide resin and a smoke retardant proportion of tin oxalate or calcium oxalate. Small amounts of zinc oxide, magnesium oxide or titanium oxide can also be included to provide cost effective smoke and fire retardant compositions. In flexible compositions a fire retardant additive such as aluminum trihydrate is used.
