Emulsion grade PVC was plasticised with 100 phr diisononyl phthalate and filled with 30 phr
of different hydrated filler-type flame retardant additives. Static heat stabilities were
determined at 200 oC 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 m2.
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.
