Sodium polymethacrylate
What is Sodium polymethacrylate?
Sodium polymethacrylate (CAS 54193-36-1) is a water-soluble anionic polymer used in industrial processing and formulation.
Where is Sodium polymethacrylate used?
- Water treatment: scale inhibitor and dispersant of suspended solids in cooling towers, boilers and industrial water circuits
- Construction: workability improver in cement and gypsum formulations, reducing water demand without compromising set strength
- Textile and paper processing: coating viscosity control and pigment dispersion
- Home care and industrial cleaning: sequestrant and anti-redeposition agent that keeps soils suspended during the wash cycle
- It functions as a dispersant, scale inhibitor and rheology modifier in aqueous systems.
Good to know: Grades are differentiated primarily by molecular weight, which affects dispersancy versus thickening performance. Buyers should confirm the molecular weight range and active content with suppliers.
Commercial specifications
- Aqueous solution, solids content typically 30% to 45%
