Sodium Tripolyphosphate STPP Supplier & Manufacturer

Sodium Tripolyphosphate

CAS: 7758-29-4

Sodium triphosphate (STPP or sodium tripolyphosphate) is an inorganic compound with formula Na5P3O10. Tripolyphosphate de sodium is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Natrium tripolyphosphate is produced on a large scale as a component of many domestic and industrial products, especially detergents.

Environmental problems associated with eutrophication are attributed to its widespread use. For those looking to source STPP powder, Shiguang, a leading STPP manufacturer, offers various formulations and provide competitive prices for bulk purchases.
