APP Ammonium Polyphosphate II
Chemical Formula : (NH4PO3) n n≥1000

Ammonium Polyphosphate II is a long-chain ammonium polyphosphate. It is non-flammable, largely insoluble in water, stable and compatible with some polymers.


Ammonium polyphosphate is an environmentally friendly halogen free flame retardant, which develops its effectiveness through phosphorus / nitrogen synergism. It is usually used with charring agent and foaming agent. The flame retardant treated material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect.
