Description

2-Propenoic Acid, 2-Methyl-, Polymer With 2,5-Furandione is a high-performance copolymer of methacrylic acid and maleic anhydride. This versatile polymer is engineered to deliver exceptional performance as a scale inhibitor, dispersant, and chelating agent in demanding industrial water treatment and process applications. It is a critical component for manufacturers in the water treatment, detergent, textile, and paper industries seeking to improve efficiency and prevent costly operational issues.

Application

• Industrial Water Treatment: Primary application as a highly effective threshold scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a superior builder and anti-redeposition agent, enhancing cleaning power by sequestering hardness ions and preventing soil from re-adhering to fabrics.
• Pulp & Paper Processing: Used as a dispersant and deposit control agent to improve pulp bleaching efficiency and prevent pitch and stickies deposition on paper machine surfaces.
• Textile Industry: Serves as an effective dispersant in dyeing processes and as a scale inhibitor in textile finishing baths to ensure consistent quality and color.
• Oilfield Applications: Employed in drilling fluids and production water treatment to control mineral scale and disperse solids, protecting downhole and surface equipment.
• Construction Chemicals: Incorporated as a superplasticizer and water-reducing agent in concrete admixtures to improve workability and final strength.

Quality Control

Our 2-Propenoic Acid, 2-Methyl-, Polymer With 2,5-Furandione is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as molecular weight distribution, solids content, and specific viscosity. Certificates of Analysis (COA) documenting these key parameters are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 moisture absorption and caking. Keep away from incompatible materials such as strong bases and oxidizing agents.
