Sodium Acrylate Copolymer

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

Where is Sodium Acrylate Copolymer used?

• Water treatment: flocculant and coagulant aid in municipal and industrial systems
• Clarification and sludge dewatering: accelerates suspended solids separation
• Detergents and industrial cleaning: anti-redeposition agent and scale inhibitor
• Textiles and paper: viscosity control in coating and sizing operations
• Agriculture: soil conditioner and water-retention aid in irrigation systems
• It prevents mineral buildup on surfaces and equipment during wash cycles.

Good to know: Molecular weight variants are commonly specified by buyers, as chain length directly determines performance in flocculation versus scale inhibition.

Commercial specifications

• Solution concentrations typically 30% to 50% active content
