Description

Poly(Acrylic Acid), Sodium Salt is a high molecular weight, water-soluble polymer widely recognized for its exceptional dispersing and sequestering properties. This versatile polyelectrolyte is crucial for controlling scale formation and particulate dispersion in aqueous systems across numerous industries. Key sectors that rely on this product include water treatment, detergent & cleaning formulations, mineral processing, and as a superabsorbent polymer precursor.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and other inorganic salts in cooling water, boiler water, and reverse osmosis systems.
• Detergents & Cleaners: Serves as a superior builder and anti-redeposition agent in laundry and dishwashing detergents, enhancing cleaning power and preventing soil from re-adhering to fabrics.
• Mineral Processing & Dispersion: Used as a dispersant for pigments, ceramics, and inorganic fillers in paints, coatings, and paper coatings to improve stability and performance.
• Superabsorbent Polymers (SAP): Functions as a key raw material or crosslinking component in the manufacture of superabsorbent polymers for hygiene products like diapers and adult incontinence pads.
• Textile Industry: Employed as a dye dispersant and anti-precipitant to ensure uniform dyeing and prevent dye agglomeration.
• Construction Chemicals: Utilized as a plasticizer and water-reducing agent in cement and concrete admixtures to improve workability and strength.
