Sodium Acrylate Copolymer

Sodium Acrylate Copolymer (CAS 25987-30-8), also supplied as acrylamide-acrylic acid copolymer sodium salt, is a synthetic polyelectrolyte used across water treatment, agriculture, and industrial processing.

Its primary commercial functions are rheology modification, flocculation, and scale inhibition in aqueous systems. In municipal and industrial water treatment, it acts as a flocculant and coagulant aid.

This material accelerates suspended solids separation in clarification and sludge dewatering processes. Detergent and industrial cleaning formulations use it as an anti-redeposition agent and scale inhibitor.

It prevents mineral buildup on surfaces and equipment during wash cycles. Textile and paper manufacturers apply it to control viscosity in coating and sizing operations, improving process consistency.

In agriculture, it functions as a soil conditioner and water-retention aid in irrigation systems. This reduces runoff and improves moisture availability to crops across various soil types.

The product is available as an aqueous solution and as a dry powder, with solution concentrations typically ranging from 30% to 50% active content. Technical grade is the standard offering.

Molecular weight variants are commonly specified by buyers, as chain length directly determines performance. This affects its efficiency in flocculation versus scale inhibition end uses.
