Description

2-Propenoic Acid, Sodium Salt, Polymer With 2-Propenenitrile is a synthetic, water-soluble copolymer of sodium acrylate and acrylonitrile. This material is valued for its exceptional superabsorbent properties and high salt tolerance, making it a critical functional polymer in demanding industrial applications. It is primarily sought by manufacturers in the water treatment, agriculture, personal care, and construction sectors for its ability to control fluid absorption and rheology.

Application

• Water Treatment: Used as a flocculant and sludge dewatering agent in municipal and industrial wastewater treatment plants.
• Agriculture & Horticulture: Employed as a soil conditioner and water-retaining agent in agricultural films, seed coatings, and hydroponics to improve water retention in soil.
• Personal Care & Hygiene: A key component in the production of superabsorbent polymers (SAP) for disposable hygiene products such as diapers, adult incontinence pads, and feminine care items.
• Construction & Civil Engineering: Acts as a viscosity modifier and water retention aid in cementitious materials, tile adhesives, grouts, and spray plasters.
• Textile Processing: Utilized as a thickening agent and print paste modifier in textile printing and dyeing processes.
• Oil & Gas Drilling Fluids: Functions as a fluid loss control additive and rheology modifier in drilling mud formulations.
• Packaging: Incorporated into specialty films and coatings for moisture control and absorbency.
• Cable Gel: Used as a water-blocking component in telecommunications and power cables.

Quality Control

Our production of Sodium Acrylate-Acrylonitrile Copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as absorption capacity, residual monomer content, particle size distribution, and viscosity are rigorously tested. Certificates of Analysis (COA) documenting purity, physical properties, and performance specifications are available for every shipment. We support compliance with relevant industry standards for hygiene, construction, and water treatment applications.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the original container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials such as strong oxidizing agents.
