Sodium Tripolyphosphate(STPP)
Molecular formula: Na5P3O10
Molecular Weight: 367.86
Standard executed: GB/T9983-2004(technical grade) QB1034-91(food grade)
CAS Number: 7758-29-4
Properties:
White powder; Melting point 622ºC; 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 thermo stability, hygroscopic, solubility and hydration heat when dissolving.
Uses:
Used as one of the main auxiliaries for synthetic detergent, synergist for soap; Water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.; As an oil contamination resistance agent in paper production. In foodstuff industry 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.
Packing And Storage:
In 25Kg/50 Kg net bag, store at a cool, dry and well ventilated place.

Product introduction SODIUM Tripolyphosphate(STPP)Property. Property:White powder or Graunlar Density is 2.52 Melting point is 622oC, soluble in water easily, but not in organic solvent. It is a fine soft water agent. CAS No.:7758-29-4 EINECS NO.:7758-29-4 Product Sodium Tripolyphosphate(STPP) Density 2.52 Melting point 622 Insoluble Organic solvent Soluble In water Molecular Weight 367.86 PH(1% aqueous solution) 9.2-10 Executive Standard GB/T 9983-2004 Pallet Based on buyer's requirment Shelf life 2 Years Proper Storage Product details 1. Apparent density 0.35-0.9g/cm3, melting point 622oC, can be soluble in water. 2. Alkaline aquesous solution, 1% aqueous solution of PH 9.7. 3. Can gradually be hydrolysed in the water into subphosphate, has a good ability to compelex metal ions. 4. Can form soluble complexes with calcium, magnesium, iron and other metal ions. 5. Can soften hard water, As an inorganic surface active, but also organin surface active agent. 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.
