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.
