Description

2-Propenoic Acid, Polymer With 2-Propenenitrile, Sodium Salt, Sodium Bisulfite-Terminated is a water-soluble, anionic copolymer derived from acrylic acid and acrylonitrile. This specialized polymer is valued for its excellent dispersing, sequestering, and scale-inhibiting properties in aqueous systems. It is a critical performance additive for industries requiring effective water treatment, mineral processing, and detergent formulation.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaner Formulation: Serves as a superior builder and dispersant in industrial and institutional cleaning products, enhancing performance by sequestering hardness ions.
• Mineral Processing: Used as a dispersant and grinding aid in the production of pigments, ceramics, and calcium carbonate, preventing particle agglomeration.
• Textile & Leather Processing: Functions as a dye dispersant and tanning auxiliary, improving color uniformity and process efficiency.
• Paper Manufacturing: Employed as a retention aid and dispersant to improve paper quality and production efficiency in pulp processing.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as a fluid loss control additive and scale inhibitor.
