Description

Poly(Acrylic Acid), Sodium Salt-Graft-Poly(Ethylene Oxide) is a high-performance, water-soluble graft copolymer designed for advanced applications requiring superior dispersing, sequestering, and water-retention properties. This unique molecular architecture combines the anionic characteristics of polyacrylate with the non-ionic, hydrophilic nature of poly(ethylene oxide) chains. It is essential for industries seeking to enhance process efficiency, product stability, and performance in aqueous systems. Key sectors utilizing this specialty polymer include water treatment, construction materials, personal care, and textile processing.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate and other inorganic salts in cooling water, boiler water, and reverse osmosis systems.
• Construction Chemicals: Serves as a superplasticizer and water-reducing agent in cement and concrete formulations, improving workability and final strength.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent, enhancing cleaning power by sequestering hard water ions and preventing soil from re-adhering to fabrics.
• Personal Care & Cosmetics: Used as a thickener, stabilizer, and film-forming agent in lotions, creams, and hair care products due to its excellent rheological modification.
• Textile & Dyeing: Employed as a dye dispersant and leveling agent to ensure uniform color uptake and improve fastness properties.
• Paper & Pulp: Utilized as a retention aid and dispersant to improve fiber distribution, drainage, and paper quality.
• Agriculture: Can be used in pesticide formulations and as a soil conditioner to improve water retention and nutrient delivery.
• Industrial Dispersions: Effective dispersant for pigments, fillers, and inorganic particles in various coating and ceramic applications.

Quality Control

Our Poly(Acrylic Acid), Sodium Salt-Graft-Poly(Ethylene Oxide) is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of molecular weight distribution, grafting efficiency, solid content, pH, and viscosity. Certificates of Analysis (COA) documenting these parameters are available upon request. We adhere to relevant industry standards and can support compliance requirements for specific applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
