Description

Poly(Acrylic Acid-Co-Maleic Acid), Sodium Salt is a high-performance, water-soluble copolymer widely utilized as a scale inhibitor and dispersant. Its unique molecular structure provides superior chelation and threshold inhibition properties against inorganic salts, making it a critical component in water treatment formulations. This product is essential for industries requiring effective control of mineral scale and particulate matter in aqueous systems.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis (RO) systems.
• Detergent & Cleaning Formulations: Acts as a builder and anti-redeposition agent in laundry and dishwashing detergents, enhancing cleaning efficiency by sequestering water hardness ions.
• Pulp & Paper Processing: Used as a dispersant for pigments and fillers like calcium carbonate and kaolin, and to control scale in the papermaking process.
• Textile Industry: Serves as a dispersing agent in dyeing processes and as an anti-scaling agent in washing and finishing baths.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals to prevent scale formation in downhole and surface equipment.
• Construction Chemicals: Incorporated as a superplasticizer and grinding aid in cement admixtures to improve fluidity and workability.

Quality Control

Our Poly(Acrylic Acid-Co-Maleic Acid), Sodium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing assay, viscosity, pH, and residual monomer content is provided with every shipment to guarantee product integrity and traceability.

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 lead to caking or reduced flowability.
