Chemical Name: Ammonium Polyphosphate
Formula:(NH4PO3)n
CAS NO:269-789-9
Applications: It can be used in expanding fireproof material, such as polyurethane, UP resin and epoxy resin. also used in the retardant of fibre, wood and plastic. APP is main ingredient of expanding retardant thermoplastic because of its high molecular weight and good heat stabilization. Especially used in the PP achieving UL94-v0 for electronic unit.
Feature:
1. Low smoke and halogen free, reduce the damage of persons or equipments in the fire;
2. Excellent weather ability, high heat stability;
3. Outstanding high performance-price ratio;
4. Improve water resistance of the paint;
5. Decrease specific gravity, increase dosage of glass fiber, and enhance surface property of thermal resin.
