Sodium Polyphosphate
Sodium polyphosphate (CAS 68915-31-1) is a condensed phosphate polymer with the repeat unit (NaPO₃)ₙ. It is a white powder or granules used as a sequestrant, dispersant and water-treatment agent. Chain length and molecular weight vary by grade; specifications are based on P₂O₅ content and viscosity rather than a single formula.
• Water treatment: prevents scaling in boilers and cooling systems.
• Food additive: sequestrant and texture modifier.
• Industrial dispersant: ceramics and pigment dispersions.
• Condensed phosphate functionality: where sequestration or dispersion is required.
