Industrial Grade Highly Purified Sodium Tripolyphosphate for Water Treatment
Sodium tripolyphosphate/ STPP
Industrial grade 96% CAS 7758-29-4
Food grade 85% CAS 7758-29-4
Molecular formula Na5P3O10
Molecular weight 367.86
- White granular or powder, showing a density of 0.35-0.90G/CM3, melting point 622 degrees Celsius
- Easily soluble in water, the aqueous solution is alkaline, and the PH of 1% aqueous solution is 9.7
- Gradually hydrolyzed into phosphite in water, and has good ionic ability of metal complexation
- Can be complexed with calcium/magnesium/iron and other metal ions to produce soluble complexes
- Softens hard water and functions as an inorganic surfactant with properties similar to organic surfactants
Mainly used for synthetic detergent as an additive/soap agent and to prevent bar soap grease precipitation and frosting. It has a strong emulsifying effect on lubricating oil and fat, and can be used to:
- Adjust the PH value of buffer soap liquid
- Industrial water softener
- Tanning and pre-tanning agent
- Dyeing agent for paint, kaolin, magnesium oxide, calcium carbonate and other industries
- Prepare suspension as a dispersant
- Drilling mud dispersant
