Description

Sodium tripolyphosphate STPP 94%

STPP Introduction:

Property: As a chained condensation compound of phosphate soluble in water,it has two existing forms: Na5P3O10(Anhydrous) and
Na5P3O10·6H2O(Crystal).
The specific gravity of Na5P3O10·6H2O is 2.12, that of Na5P3O10is 0.5-0.6,melting point for both is 622°C. Anhydrous Na5P3O10 is
capable of absorbing humidity with its aqueous solution being alkalinity .It can have emulsification, suspension and dispersion of mud and oil; it has strong buffering effects with PH value between 4.3-14.
