Brief introduction:
APP(ammonium polyphosphate) is mainly polymerized from monomeric diphosphorus pentaoxide(P2O5) and diammonium hydrogenorthophosphate(DAP)
APP is flame retardant using expansion mechanism.
APP decomposes ammonia gas and polyphosphoric acid at 275 ℃. Ammonia dilutes the oxygen concentration and at the same time expands and loosens the carbon layer to isolate heat.
APP is halogen free, environmental friendly.
TF-251 is a new type of environment-friendly flame retardants with P-N synergies, which is suitable for polyolefin , thermoplastic elastomer and so on. TF-251 have excellent char forming properties. When the flame retardant product is burning, the carbonized layer will be formed on the surface to isolate oxygen so that it can prevent flame spreading. The density of final product with TF-251 is low and low smoke will be produced when burning . Problems such as hydration and salinification will not emerge.
