Description

Acrylic Acid Maleic Acid Copolymer is a high-performance, water-soluble polymer synthesized from acrylic acid and maleic acid monomers. This versatile copolymer is valued for its exceptional scale inhibition and dispersancy properties in aqueous systems. It is a critical additive for water treatment, detergent formulation, and industrial cleaning applications, where it effectively controls mineral deposits and enhances process efficiency.

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 reverse osmosis systems.
• Detergent & Cleaning Formulations: Used as a builder and anti-redeposition agent in laundry detergents and industrial cleaners to sequester hardness ions and prevent soil from re-adhering to fabrics.
• Pulp & Paper Processing: Serves as a dispersant and deposit control agent to improve pulp bleaching efficiency and prevent scale formation in paper machines.
• Textile Industry: Applied in dyeing and finishing processes to prevent scale buildup on equipment and ensure uniform dye distribution.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments and production systems to maintain well productivity.
• Personal Care Products: Utilized as a viscosity modifier and stabilizer in certain cosmetic and personal care formulations.
