Description

2-Propenenitrile, Homopolymer, Hydrolyzed, Sodium Salt is a water-soluble, anionic polyelectrolyte derived from polyacrylonitrile. This specialized polymer is valued for its exceptional flocculation, dispersion, and water-binding properties, making it a versatile performance additive. It is primarily utilized in industries such as water treatment, paper manufacturing, textiles, and personal care, where its ability to modify rheology and interact with charged particles is critical.

Application

• Water Treatment: Acts as a highly effective flocculant and coagulant aid for clarifying process water and wastewater, promoting the settling of suspended solids.
• Paper Industry: Used as a retention and drainage aid to improve fiber and filler retention on the wire, enhancing paper quality and production efficiency.
• Textile Sizing & Finishing: Serves as a sizing agent for yarns and a thickener in printing pastes, providing excellent film-forming and viscosity control.
• Personal Care & Cosmetics: Functions as a stabilizer, thickener, and film-forming agent in products like hair gels, creams, and lotions.
• Ceramics & Construction: Employed as a binder and dispersant in ceramic slips and cement formulations to improve green strength and workability.
• Oil & Gas Drilling: Utilized in drilling muds as a fluid loss control additive and shale inhibitor.
• Agriculture: Used as a soil conditioner and in pesticide formulations to improve adhesion and slow release.
• Detergents: Acts as an anti-redeposition agent and soil suspender in laundry and dishwashing formulations.

Quality Control

Our production of Hydrolyzed Polyacrylonitrile, Sodium Salt adheres to stringent quality management protocols. Each batch is tested against key parameters including degree of hydrolysis, molecular weight distribution, viscosity, and ionic character to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
