What Is Sodium Tripolyphosphate STPP?

Sodium tripolyphosphate(STPP), also known as sodium triphosphate, pentasodium triphosphate is a kind of amorphous water-soluble linear polyphosphate in terms of its chemical structure. Sodium tripolyphosphate formula is Na5P3O10 and the molecular weight is 367.86. In appearance, it is white or colorless crystals, which flows well, dissolves in water easily. The aqueous solution is alkaline, the PH value of 1% aqueous solution is 7.9. STPP chemical is a widely used phosphate chemical, which can be divided into food grade and industrial grade sodium tripolyphosphate 94% depends on the uses. Both the two types, Chemate can manufacture and supply. Inquiry us to tell us your requirements now, quotation will be sent to you very quickly.
