Abstract

Emulsion grade poly(vinyl chloride) was plasticized with 100 phr of diisononyl phthalate and filled with 30 phr of different hydrated filler-type flame-retardant additives. Static heat stabilities were determined at 200°C by following the time dependence of hydrogen chloride evolution. Fire-retardant performance was studied with a cone calorimeter at a radiant flux of 35 kW m−2. The layered double hydroxide outperformed the other fillers with regard to improving static heat stability and also with respect to most fire-retardant performance indices.
