Description

Acrylic Acid/ Acrylonitrile Copolymer, Sodium Salt is a synthetic, water-soluble polyelectrolyte derived from the copolymerization of acrylic acid and acrylonitrile, subsequently neutralized to its sodium salt form. This copolymer is valued for its exceptional thickening, dispersing, and water-retention properties, making it a critical performance additive in numerous industrial processes. It is primarily sought by manufacturers in the water treatment, textile, paper, and personal care industries for its ability to modify rheology and stabilize complex formulations.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems.
• Textile Processing: Used as a thickener and binder in pigment printing pastes and as a sizing agent to improve yarn strength.
• Paper Manufacturing: Functions as a dry strength additive and retention aid to enhance paper quality and production efficiency.
• Personal Care & Cosmetics: Serves as a primary rheology modifier and stabilizer in hair gels, creams, and lotions.
• Detergents & Cleaners: Enhances the suspension of dirt and prevents redeposition in liquid and powder detergent formulations.
• Ceramics & Construction: Employed as a plasticizer and water-retention agent in ceramic slips, tile adhesives, and cement-based materials.
