                                              High Quality Sodium Tripolyphosphate(STPP) CAS 7758-29-4 From China


Sodium tripolyphosphate is an inorganic compound with the chemical formula Na5P3O10. It is an amorphous water-soluble linear polyphosphate and is commonly used in food as a moisture retainer, quality improver, pH regulator, and metal chelator.

physicochemical property:

melting poin: 622ºC
density: 2.52g/cm3
appearance: White crystalline powder
solubility: It is easily soluble in water and the aqueous solution is alkaline.

Trisodium phosphate has two crystalline forms: type I (high-temperature type) and type II (low-temperature type). The difference lies in the different bond lengths and bond angles between the two. Their chemical properties are the same, but the thermal stability and hygroscopicity of type I are higher than those of type II.
