AMMONIUM POLYPHOSPHATE (APP)
Molecular Formula: (NH4)n+2PnO3n+1
CAS NUMBER: 68333-79-9
Properties:
As per polymerization, APP can be divided into three types, i. E high polymerization APP, medium polymerization APP and low polymerization APP. The higher polymerization is, the less solubility will be. As per the structure APP may be divided into two type, namely crystalline APP and amorphorous APP. Crystalline APP is a water insoluble and long-chain polyphosphate, and it has 5 variants named as variant I to V, As a white powder water insoluble APP is not deliquescent and has got very good compatibility with other aids; Water soluble APP is apt to cake under normal temperature, but this will not affect it performance and application. APP is a poisonless product.
Use:
As a flame-proof agent, it is mainly applied to flame-proof coatings, plastic, rubbers, wood and paper etc., besides it can also be used as a highly concentrated NP fertilizer or feed additive.
Packing:
25kg/50kg woven PP bags lined with PE bags inner. Store in dry and well ventilated places, and never pile it in the open air.
