Comprehensive study of the degradation of an intumescent EVA-based material during combustion

摘要

In this work, we have studied the evolution of anflame retardant intumescent EVA-based material duringcombustion. The formulation uses an original concept of thelaboratory, i.e., use of char forming polymer (here the polyamide-6)as carbonisation agent associated to a carbonisation catalyst in anintumescent formulation. The fire behavior was modelled usingthe cone calorimeter and we have explained the evolution of therate of heat release curve in terms of chemistry of the system usingFTIR and solid state NMR.
