STPP CAS NO.7758-29-4

SODIUM TRIPOLYPHOSPHATE 94%min technical grade  25kg/bag

White powder, melting point 622°C, easily soluble in water. Sodium tripolyphosphate 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. Sodium tripolyphosphate is a surfactant, and has got outstanding emulsification to lubricants and fat.

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. And as an oil contamination resistance agent in paper production.
