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.

We can supply & export to international customers STPP SODIUM TRIPOLYPHOSPHATE for Caramic industries & factories & also we can export Potassium Feldspar Sodium Feldspar & Kaolin as well. pls send us your enquiries if you want to procure quality materials from our company Thank you !
White powder, apparent density:0.35-0.90g/ml, melting point: 622�°C, easily dissolving in water; water solution is alkaline (PH value of 1% solution is 9.7); can hydrolyze into phosphate in water, has good ability in complexing metal ions; can be used to soften water; has some surfactant properties.
1.In detergents
The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dictations tightly and prevents them from interfering with the sulfonate detergent.
2.Food Applications
STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe.".
3.Other Uses
Other uses (hundreds of thousands of tons/years) include "ceramics, leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze.

it is white powder, 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 is used as one of the main auxiliaries agent for synthetic detergent, synergist for soap, tanning agent for making leather, softener for water industry, an effective dispersion agent for suspension treatment of painting, kaolin, magnesium oxide, calcium carbonate and drilling mud etc. resistance agent of the oil contamination in paper production.
