Stpp Ceramic Grade
 Ceramic stpp 94%

STPP 94%

Chemical Formula: Na5P3O10

Molecular Weight:367.86

Properties: White powder

Packing:: 25kgs pp bag(lined with plastic bag)

Sodium tripolyphosphate STPP

 

Properties:

 

 White powder; Melting point 622 °C ; Easily soluble in water; It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity . It is a surfactant, and has got outstanding emulsification to lubricants and fat. It has different bulk density, i.e. low density 0.35-0.5g/cm 3 , medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm 3 . This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .

Application:

 

Main part being used as sapide helps the agent , soap synergist , water softener , processes hides giving tanning agent , dyeing an assistant, the effective powder that suspension liquid sells at reduced prices such as paint , advanced age soil , magnesia , calcium carbonate lama, makes paper using the greasy dirt aseptic , organic synthesis catalysator. Also be used petroleum products to refine , rubber whey bestowal , metal industry and medicine industrial to do the dispersant, but the solvation, use being unable to have broad as well as domestic bird processes aspect in synthal , food industry.
