Based on 1 Customer Validation

Sodium polyphosphate, crystal,+200 mesh, 96% is an inorganic polyphosphate that also serves as a stabilizer, dispersant, chelating agent, and coacervate-forming agent. Sodium polyphosphate provides electrostatic stabilization for mineral and material suspensions, but its dispersing efficacy decreases under acidic pH, high temperature, high calcium concentration, or a combination of these conditions. Sodium polyphosphate can chelate alkaline earth metals, reduce solution pH, and alter the rate of pH decline at a divalent cation/phosphorus molar ratio of 0.18. Sodium polyphosphate forms coacervates with smaller divalent cations and precipitates with larger divalent cations, where the functional requirements of cations depend on polyphosphate concentration, average degree of polymerization, and cation type.
