Water Soluble Fertilizer>>Phosphate

Ammonium Polyphosphate(APP)

Molecular formula: (NH4)n+2PnO3n+1

CAS Number:68333-79-9

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, As water insoluble APP is not deliquescent and has got very good compatibility with other aids; Water soluble APP can be used as high nutrient fertilizer.

Main Advantages
      ·  100% water soluble
      ·  APP is a high nutrient of Nitrogen and P, it can also be used NP fertilizer.
Packing and Storage
Packed In 25kg,50kg net WPP/PE bags,store at a cool,dry and well ventilated place.
