Description

2-Butenedioic Acid (2Z)-, Polymer With Sodium 2-Propene-1-Sulfonate is a high-performance, water-soluble copolymer derived from maleic acid and allylsulfonic acid sodium salt. This specialized polymer is engineered to deliver exceptional scale inhibition and dispersancy, making it a critical component in water treatment and industrial process formulations. It is primarily utilized by professionals in the chemical, water treatment, and oilfield industries to control mineral scale and prevent fouling in cooling towers, boilers, and reverse osmosis systems.

Application

• Industrial 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 desalination (RO) systems.
• Oilfield Chemicals: Used in drilling fluids and production chemicals to prevent scale deposition in downhole equipment and pipelines, enhancing operational efficiency.
• Detergent & Cleaning Formulations: Functions as a builder and anti-redeposition agent in industrial and institutional cleaning products, improving performance in hard water.
• Pulp & Paper Processing: Serves as a dispersant and deposit control agent to prevent pitch and scale formation during pulp bleaching and papermaking.
• Textile Industry: Employed in dyeing and finishing baths to inhibit scale and disperse impurities, ensuring consistent color and fabric quality.
• Construction Chemicals: Incorporated into cement admixtures and gypsum slurries as a plasticizer and water reducer to improve workability and final strength.
