Pentasodium Triphosphate, Sodium Triphosphate or Sodium Tri Polyphosphate (STPP) - Anhydrous
Grades We Manufacture :
Sodium Tri Polyphosphate Anhydrous Industrial Grade
Formulation :
Anhydrous
- 3H3PO4 + 5NaOH = Na5P3O10 + 7H2O
- 6H3PO4 + 5Na2CO3 = 2Na5P3O10 + 5CO2 + 9H20
Sodium triphosphate is the sodium salt of the polyphosphate, which is the conjugate base of tri-phosphoric acid. STPP is a colorless salt, which exists as anhydrous and also as hexahydrate.
Its wide spread use is well known in detergent industries. The most common method of preparation is by reacting Mono Sodium and Disodium Phosphates.
Application :
- Sodium Tri polyphosphate forms a key component of commercial detergents and is used widely for that purpose
- STPP serves as a food preservative, used to preserve meat, poultry, animal feeds and seafood
- STPP is used in ceramics to increase viscosity of the glazes
- Other uses of STPP are leather tanning, in flame retardants, paper, anticorrosion pigments, textile, rubber manufacture, etc
