Product Description

                                                             Sodium Tripolyphosphate STPP

 

STPP or Sodium Tripolyphosphate is an inorganic compound with formula Na5P3O10. STPP,Sodium Tripolyphosphate  is the
sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium tripolyphosphate is
produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4,
under carefully controlled conditions.
