Product Description


Property:


STPP or sodium triphosphate is an inorganic compound with formula Na5P3O10. STPP,Sodium Tripolyphosphate  is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions..

 It can complex with calcium, magnesium, iron and other metal ions to form a soluble complex. It softens hard water. As an inorganic surfactant, it has some properties of organic surfactant

White powder, apparent density 0.35-0.90g/cm3, melting point 622c. Soluble in water. Aqueous solutions are alkaline and 1% aqueous solutions have a PH of 9.7. Hydrolyzed into phosphite in water, it has good complexing ability of metal ions.

Application and performance :

Sodium tripolyphosphate is mainly used for synthetic detergents as additives, soap synergies and prevent soap grease from seeping out and frosting. It has strong emulsifying effect on lubricating oil and fat, which can be used to adjust the PH value of buffer soap, soft water agent, leather pre-tanning agent, dyeing assistant, paint, kaolin, magnesium oxide, calcium carbonate and other industrial suspensions as dispersant, drilling mud dispersant and paper industry as anti-grease agent.
