• Detailed Description:

  Chemical Name：Sodium Tripolyphosphate
  　　Synonyms：Penta sodium Triphosphate
  　　Molecular formula: Na5P3O10
  　　Standard executed : GB25566-2010
  　　Properties:
  　　White powder; Melting point 622°C; Easily soluble in water; It has got salient chelating capacity to ions of Ca and Mg etc. and can soften hard water to make suspension solution become into clear solution; It has got weak alkalinity but no corrosiveness. 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/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. This product has two crystalline forms, namely Type I (high temperature type) and Type II (low temperature type). The chemical properties of the two types are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving .
  　　Application:
  　　Sodium tripolyphosphate is used in the food industry as an emulsifying agent and quality improver agent, for example, including processed meat processed seafood, processed cheeses, noodles product. it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
  　　Packaging：
  　　25KG,inner plastic and outer plastic or paper.
