Sodium polymethacrylate

Sodium polymethacrylate (CAS 54193-36-1) is a water-soluble anionic polymer used across industrial processing and formulation. It functions as a dispersant, scale inhibitor, and rheology modifier in aqueous systems.

In these systems, controlling particle behavior or viscosity is critical to process performance. In water treatment, it inhibits scale formation and disperses suspended solids in cooling towers, boilers, and industrial water circuits.

Construction product manufacturers incorporate it into cement and gypsum formulations to improve workability. This allows for a reduced water demand without compromising the final set strength of the materials used.

Textile and paper processors use it to control coating viscosity and improve pigment dispersion across substrate surfaces. This ensures a uniform application and high-quality finish for various industrial textile products.

In home care and industrial cleaning formulations, it acts as a sequestrant and anti-redeposition agent. It prevents mineral buildup and keeps soils suspended during the wash cycle for more effective cleaning results.

The product is supplied as an aqueous solution, with solids content typically ranging from 30% to 45%, and less commonly as a dry powder. Grades are differentiated primarily by their specific molecular weight.

Molecular weight directly affects performance in dispersancy versus thickening applications. Technical and industrial grades are standard, and buyers should confirm the molecular weight range and active content with suppliers.

Matching these specifications to the intended process ensures optimal performance. Always verify that the material meets the necessary industrial requirements for your specific manufacturing or formulation needs.
