Abstract
Char formation that preserves the structural integrity of the polymer is one of the most efficient methods of reducing its flammability. Enhanced char formation from polymers such as PVC may also be associated with a decrease in smoke production, as is observed when the polymer is modified by a flame retardant smoke suppressant (FRSS) complex. A correlation had been made between the FRSS characteristics and char morphology. The effect of different flame retardant smoke suppressants on char formation has been highlighted.
