Ammonium Polyphosphate (APP)
[CAS No.]: 68333-79-9
[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.
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.
[Storage and transportation]: Handle with care, keep airtight and dry.

Ammonium polyphosphate Usage And Synthesis
|Description||Ammonium polyphosphate (APP) is an organic salt of polyphosphoric acid and ammonia. As a chemical, it is non-toxic, environmentally friendly and halogen-free. It is most commonly used as a flame retardant, selection of the specific grade of ammonium polyphosphate can be determined by the solubility, Phosphorus content, chain length and polymerization degree. The chain length (n) of this polymeric compound can be linear or branched. Depending on the polymerization degree, there are two main families of ammonium polyphosphate: Crystal phase I APP (or APP I), and Crystal phase II APP (or APP II).
