Description

Poly(Styrenesulfonic Acid/Maleic Acid), Sodium Salt is a water-soluble anionic polyelectrolyte copolymer. This versatile polymer is valued for its excellent dispersing, chelating, and scale-inhibiting properties in aqueous systems. It is a critical component for industries requiring high-performance water treatment, mineral processing, and detergent formulations.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a builder and co-builder, enhancing cleaning power by sequestering hardness ions like calcium and magnesium.
• Mineral Processing: Used as a dispersant in pigment slurries, ceramic processing, and ore beneficiation to prevent particle agglomeration.
• Textile & Paper Industries: Serves as a dye dispersant, soil release agent, and processing aid to improve product quality and manufacturing efficiency.
• Oilfield Chemicals: Employed in drilling muds and completion fluids for its rheological control and scale inhibition properties.
• Personal Care Products: Used in select formulations as a viscosity modifier and stabilizer.
