Ammonium Polyphosphate TY****4: APP TY****4 TY****4 is short-chain crystal phase ammonium polyphosphate. They are non-flammable, largely insoluble in water, stable and compatible with other polymers. TY****4 is environmentally friendly halogen free flame retardant, which develops its effectiveness through phosphorus / nitrogen synergism. They are usually used with charring agent and foaming agent.
