The effect of magnesium hydroxide, hydromagnesite and layered double hydroxide on the heat stability and fire performance of plasticized poly(vinyl chloride)
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.
