Description

Sodium Acrylates/Acrylonitrogens Copolymer is a synthetic, water-soluble polymer designed for high-performance applications requiring superior water absorption and retention. This copolymer is valued for its unique rheological properties and ionic character, making it an essential functional additive in various industrial processes. Key industries that utilize this material include personal care, water treatment, agriculture, and specialty coatings, where it acts as a thickener, suspending agent, or superabsorbent polymer (SAP).

Application

• Personal Care & Cosmetics: Acts as a primary thickener, stabilizer, and film-forming agent in creams, lotions, hair gels, and sunscreens to enhance texture and product stability.
• Water Treatment: Used as a flocculant and coagulant aid to clarify process water and wastewater by promoting the aggregation of suspended solids.
• Agriculture & Horticulture: Employed as a soil conditioner and water-retention agent to improve moisture availability for plants and reduce irrigation frequency.
• Industrial Coatings & Adhesives: Functions as a rheology modifier and thickener in water-based paints, coatings, and adhesive formulations to control viscosity and application properties.
• Textile Processing: Serves as a sizing agent, thickener for printing pastes, and finishing agent to improve fabric hand feel and durability.
• Paper Manufacturing: Utilized as a retention aid and dry-strength additive to improve paper quality, fiber retention, and production efficiency.
• Oil & Gas Drilling Fluids: Applied as a fluid loss control additive and viscosifier in drilling muds to maintain wellbore stability.
• Detergents & Cleaners: Incorporated as an anti-redeposition agent and soil suspension polymer to enhance cleaning efficacy in laundry and dishwashing formulations.

Quality Control

Our Sodium Acrylates/Acrylonitrogens Copolymer is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of molecular weight distribution, residual monomer content, viscosity, and absorption capacity. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are available for every shipment. We adhere to relevant ISO standards and can support compliance requirements for specific market regulations.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials such as strong oxidizing agents.
