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.

Stpp (sodium tripolyphosphate)
Properties:
White powder; melting point 622ípc; 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, and solubility and hydration heat when dissolving.
