Description

Sodium Polymethacrylate is a high-performance, water-soluble anionic polymer derived from methacrylic acid. This versatile compound is valued for its exceptional dispersing, sequestering, and scale-inhibiting properties in aqueous systems. It is a critical additive for industries requiring superior water treatment, efficient mineral processing, and advanced formulation stability.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Detergents & Cleaners: Functions as a superior builder and dispersant, enhancing cleaning power by sequestering hardness ions (Ca²⁺, Mg²⁺) and preventing soil redeposition.
• Mineral Processing & Pulp/Paper: Used as a dispersant for pigments, fillers (like calcium carbonate), and clays to improve process efficiency and product quality.
• Construction Chemicals: Employed as a superplasticizer and water-reducing agent in cement and concrete formulations to improve workability and strength.
• Personal Care & Cosmetics: Serves as a thickening, suspending, and stabilizing agent in creams, lotions, and hair care products.
• Textile & Leather Processing: Utilized as a dispersant for dyes and finishing agents to ensure uniform color and treatment.
• Paints & Coatings: Acts as a pigment dispersant and stabilizer to prevent settling and maintain viscosity.
• Oilfield Chemicals: Applied in drilling fluids as a rheology modifier and fluid loss control additive.
