Sodium Tripoly Phosphate(STPP) (CAS No.: 7758-29-4 )
Executive Standard: GB9983-88
Molecular Formula: Na5P3O10
MW: 367.86 .
Character: It is white powder; Byname is Pent-sodium Phosphate; Melting point is 622'C;It has salient chelating capacity to ions of Ca, Mg etc; It can soften the hard water to make suspension become into the clear solution; it has weak alkalinity but no corrosiveness. It is a surfactant which has outstanding emulsification for 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 kinds of crystalline forms, namely Type I (the type of high temperature) and Type II (the type of low temperature). The chemical characters of the two types are the same, and the difference between them lies in the thermo stability .

Sodium tripolyphosphate is an inorganic substance with chemical formula Na5P3O10. It is a kind of amorphous water-soluble linear polyphosphate. It is used as water retention agent, quality improver, pH regulator and metal chelator Main Application: Industrial use Used as detergent, auxiliary, also used in petroleum, metallurgy, mining, paper making, water treatment, etc.. Mainly used as synthetic detergent additives, synergist for soap and soap to prevent a fat separation and bloom. It has a strong emulsifying action on lubricating oils and fats and can be used to regulate the pH of buffer soap solutions. Water softener for industrial water. Tanning agent. Dyeing assistants. Paint, kaolin, Magnesium Oxide, calcium carbonate and other industries in the preparation of suspension as a dispersant. Drilling mud dispersant. The paper industry is used as an anti oil agent. Canned food, for the food industry in fruit juices, dairy products, soy milk and other quality improvement agent, water retention agent. Mainly for canned ham tender, broad beans in the skin softening, it can also be used as a thickening agent and softener.
