Description

2-Butenedioic Acid (Z)-, Polymer With 2-Propenenitrile And 2-Propenoic Acid, Ammonium Salt is a water-soluble, anionic copolymer based on maleic acid, acrylonitrile, and acrylic acid. This specialized polymer is engineered to function as a highly effective dispersant and scale inhibitor, offering superior performance in demanding aqueous systems. It is a critical material for industrial water treatment, mineral processing, and detergent formulation, where it controls crystallization and prevents unwanted deposits.

Application

• Industrial Water Treatment: Primary application as a threshold scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a builder and anti-redeposition agent in liquid and powder detergents, enhancing cleaning efficiency and preventing soil from re-adhering to fabrics.
• Mineral Processing & Dispersion: Used as a dispersing agent for inorganic pigments, fillers (like calcium carbonate), and clay slurries to prevent agglomeration and ensure stability.
• Pulp & Paper Industry: Employed in process water systems to control scale and as a dispersant for paper coatings and fillers.
• Textile Auxiliary: Functions in dyeing and printing processes to improve color yield and prevent dye agglomeration.
• Oilfield Chemicals: Potential use in drilling muds and production chemicals as a scale control additive.
