Hydrophilic Ammonium Polyphosphate (Phase-II) Treated By Silane
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-201W is a kind of silane treated APP phase II. Its advantages are excellent water resistance and good compatibility with organic polymers and resins. It is hydrophilic.
