Mechanism of endothermic / flame retardancy



Endothermic effect: some flame retardant agent in high heat capacity under high temperature phase change, dehydration or dehydrohalogenation and endothermic decomposition reaction, reduce the surface of fiber material and flame temperature reduction, slow pyrolysis rate, inhibit the formation of combustible gases. Such as when to release the 3 alumina trihydrate decomposition of a water molecule into the gas phase dehydration need to consume a large amount of heat.
