Be used for
Industrial grade Sodium Hexametaphosphate(STPP) Application:
1. Sodium tripolyphosphate is used for meat processing, synthetic detergent formulations, textile dyeing, also used as dispersing agent, solvent etc.
2. It is used as soft water, also used in confectionery industry.
3. It is used as power stations, locomotive vehicle, boiler and a fertilizer plant cooling water treatment, water softener. It has strong ability to Ca2+ collaterals, per 100g to complex 19.5g calcium , and because SHMP chelation and adsorption dispersion destroyed the normal process of calcium phosphate crystal growth, it prevents the formation of calcium phosphate scale. Dosage is 0.5 mg/L, prevent that scaling rate is up to 95%~100%.
4. Modifier; emulsifier; buffer; chelating agent; stabilizer. Mainly for canned ham tenderization; canned broad beans in the Yuba softening. Can also be used as soft water, pH regulator and thickening agent.
5. It is used for synergist for soap and preventing bar soap grease precip.
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.

Sodium tripolyphosphate has a wide range of uses, because of its dispersion, chelating, gelling, emulsification, pH buffer and other functions, so it can be widely used in food processing, industrial manufacturing, medical and other fields.
1, food processing: sodium tripolyphosphate belongs to inorganic substances, can be used as food additives, play a role in regulating the pH of food, improve the taste of the effect, but also lock the water, help to achieve the purpose of food preservation, can extend the shelf life of food, can make the food tenderized, but also to a certain extent to improve the flexibility of the food. Because of its good dispersing ability, it can make the taste of food more delicate and smooth, so sodium tripolyphosphate is also mostly used in meat, dairy products, canned goods, juice drinks and other foods.
2ã??Industrial manufacturing: Sodium tripolyphosphate can be used in industry to purify water, also can be used as bleach, deodorant, antiseptic, made into soap, detergent to use, also can be used as industrial water softeners, leather pre-tanning agent, dyeing auxiliaries, coatings, etc., widely used in industrial manufacturing.
3 Medical use: Sodium tripolyphosphate is a kind of ionic crosslinking agent, which can be applied to the production of medical hemostatic materials.
