Description

Poly(Styrenesulfonic Acid-Co-Maleic Acid), Sodium Salt is a high-performance, water-soluble copolymer widely utilized for its exceptional dispersing and chelating properties. This versatile material is crucial for controlling scale formation and stabilizing complex formulations in demanding aqueous systems. It serves as a key functional additive for manufacturers in the water treatment, textile processing, and detergent industries, where consistent quality and reliable performance are paramount.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a superior builder and anti-redeposition agent, enhancing cleaning power and preventing soil from re-depositing onto fabrics.
• Textile Processing: Used as a dye dispersant and leveling agent to ensure uniform color uptake and improve the quality of dyed fabrics.
• Paper & Pulp Industry: Serves as a dispersant and retention aid in papermaking processes to improve sheet formation and drainage.
• Mineral Processing: Applied as a dispersant in slurry transport and mineral beneficiation to prevent particle agglomeration.
• Ceramic & Cement Additive: Helps in the dispersion of particles in ceramic slips and cement mixtures, improving workability and final product strength.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals for scale control and as a fluid loss additive.

Quality Control

Our Poly(Styrenesulfonic Acid-Co-Maleic Acid), Sodium Salt is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for molecular weight distribution, solids content, pH, and ionic character. A Certificate of Analysis (COA) documenting purity, performance, and safety data is provided with each shipment to guarantee consistency and compliance for your industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect performance. Keep away from incompatible materials such as strong oxidizing agents.
