Original product description
High Quality 94% Sodium Tripolyphosphate (STPP) Used In Detergent Paint Water treatment Sodium tripolyphosphate is a white powder crystal with good fluidity. The density of type 1 is 2.62g/cm³, and the density of type 2 is 2.57g/cm³. Melting point 622ºC.
It is easily soluble in water, and its aqueous solution is alkaline. Solubility: soluble in water, 20g/100mL (20ºC) Sodium triphosphate (STPP or sodium tripolyphosphate) is an inorganic compound with formula Na5P3O10.
It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It 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 widespreaduse.
