Ammonium polyphosphate (APP) is a mixture of ammonium orthophosphate and various ammonium polyphosphates, which mainly contains ammonium pyrophosphate, ammonium tripolyphosphate and ammonium tetraphosphate, and only a small amount of ammonium polyphosphate with longer chain exists.
Flame retardant Ammonium polyphosphate Mflam AP231 can be used in adhesive and sealants, PU foam, PP, non-woven textile for back coating, etc.
Ammonium polyphosphate is not only used as the ingredient of various fertilizers, but also as an important chemical for extinguishing forest and mountain fires, and as a fire-retardant impregnating agent for wood.
