Description

Butanedioic Acid, Methylene-, Disodium Salt, Polymer With 2-Propenamide is a high-performance, water-soluble copolymer derived from maleic acid and acrylamide. This specialized polymer is engineered to function as an effective scale inhibitor and dispersant in demanding aqueous systems. It is a critical component for industries requiring robust water treatment solutions, mineral processing aids, and detergent formulations where control over inorganic deposits is paramount.

Application

• Industrial Water Treatment: Acts as a highly effective threshold scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a superior builder and anti-redeposition agent, enhancing cleaning power and preventing inorganic salt deposits on fabrics and surfaces.
• Mineral Processing & Pulp & Paper: Functions as a dispersant to prevent agglomeration and scaling of inorganic particles, improving process efficiency in mining, pigment slurry, and paper production.
• Oilfield Applications: Used in drilling fluids and production chemicals to control scale formation in downhole and topside equipment, protecting infrastructure.
• Textile & Dyeing Auxiliary: Helps in dispersing dyes and preventing scale buildup on machinery, ensuring consistent color and fabric quality.
• Ceramic & Construction: Acts as a plasticizer and grinding aid in ceramic slips and cement admixtures, improving workability and final product strength.

Quality Control

Our production of Butanedioic Acid, Methylene-, Disodium Salt, Polymer With 2-Propenamide adheres to a strict quality management system. Each batch undergoes rigorous testing for key parameters including polymer molecular weight distribution, active content, residual monomer levels, and performance in standard scale inhibition tests. Certificates of Analysis (COA) documenting these results are available for every shipment to ensure traceability and compliance with your specifications.

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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or absorption of moisture. Keep away from strong oxidizing agents.
