Tpsin flame retardant mechanism (P-N-Si-C)Phosphorus provides acid source (dehydrating agent): reacts with resin to promote the formation of carbonized products.
Nitrogen provides gas source (foaming agent): can make the system expand and foam, and also promote the formation of carbonized layer, forming a porous foam carbon layer.
Silicon provides thermal stability (silicon oxide): can increase thermal stability at high temperature, greatly improve the residual carbon rate and flame retardancy, and reduce the emission of smoke and toxicity during combustion.
