Ammonium Polyphosphate (APP)

[Formula]: (NH4PO3)n
[CAS No.]: 68333-79-9
[Product classification]:APP101/APP102
[Appearance]: white powder
[Applications]:It can be used in expanding fireproof material, such as polyurethane, UF resin and epoxy resin. Also can be used in the retardant of fiber, wood and plastic. APP is main ingredient of expanding retardant thermoplastic because of its high molecular weight and good heat stability.UL94-V0 for electronic unit made from PP shall be achieved with loading this product. 
[Feature]:
　　1.APP102 has excellent weathering properties and high stability. It can improve the water resistance of products in the coating. It can  reduce the proportion of product, improve the quantity of glass fibre and improve the surface properties of the product in  the thermosetting resin products. 
　　2. App101 has strong moisture resistance, alkaline PH value and low water solubility after surface treatment.
[Packing]: 25Kg kraft bags.
[Capacity]: 2000T/a
