Description

2-Propenamide, Homopolymer, Hydrolyzed, Sodium Salts is a synthetic, water-soluble polymer derived from the partial hydrolysis of polyacrylamide. This compound is valued for its exceptional flocculation, thickening, and water-retention properties, making it a critical performance additive in numerous industrial processes. It is primarily sought by professionals in the water treatment, paper manufacturing, mineral processing, and enhanced oil recovery sectors for its ability to modify fluid rheology and separate solids from liquids efficiently.

Application

• Water & Wastewater Treatment: Acts as a highly effective flocculant for clarifying drinking water and treating industrial effluent.
• Paper & Pulp Industry: Used as a retention and drainage aid, as well as a dry-strength agent to improve paper quality and production efficiency.
• Mineral Processing: Serves as a selective flocculant and settling aid in the beneficiation of ores such as coal, iron, and potash.
• Enhanced Oil Recovery (EOR): Functions as a viscosifier in polymer flooding to improve sweep efficiency and increase oil yield from reservoirs.
• Agriculture & Soil Conditioning: Applied as a soil stabilizer and hydrogel to reduce erosion, improve water infiltration, and retain moisture.
• Textile & Dyeing: Utilized as a thickener in printing pastes and as a processing aid to improve fabric handle and dye uniformity.
• Personal Care & Cosmetics: Employed as a film former, thickener, and stabilizer in products like creams, lotions, and hair gels.
• Construction & Civil Engineering: Used in cementitious mixtures and grouts to improve workability, reduce water loss, and enhance adhesion.

Quality Control

Our production of Hydrolyzed Polyacrylamide adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis for key parameters including degree of hydrolysis, molecular weight distribution, viscosity, and residual monomer content. Certificates of Analysis (COA) documenting these results are provided with every shipment. Our quality system is designed to support compliance with relevant industry and regulatory expectations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after opening to prevent caking or degradation due to moisture absorption. Keep away from incompatible materials.
