Description

2-Propenoic Acid, Polymer With Ethenylbenzene And 2,5-Furandione, Ammonium Salt is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer combines the robust properties of acrylic acid and styrene with the reactive functionality of maleic anhydride, delivered in a convenient ammonium salt form. It is essential for industries requiring advanced dispersants, scale inhibitors, or rheology modifiers, particularly in water treatment, construction, and detergent formulations where effective performance under varied pH conditions is critical.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to control calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Used as a superplasticizer and grinding aid in cement and concrete admixtures to improve workability, reduce water content, and enhance final strength.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in industrial and institutional cleaning formulations to improve soil suspension and inhibit inorganic salt precipitation.
• Paints & Coatings: Serves as a pigment dispersant and rheology modifier in aqueous coating systems to ensure stable color development and optimal application properties.
• Textile Processing: Employed as a dye dispersant and leveling agent to achieve uniform dye uptake and brilliant color fastness on fabrics.
• Paper Manufacturing: Utilized in pulp processing and paper coating as a retention aid and dispersant to improve sheet formation and filler retention.
• Oilfield Chemicals: Applied in drilling fluids and production chemicals as a scale inhibitor and clay stabilizer to maintain wellbore integrity and flow assurance.
• Industrial Cleaning: Key component in formulations for metal cleaning and acid cleaning to prevent redeposition of dissolved salts and particulates.
