Description

Polymethacrylamide CAS NO 25722-14-9 is a synthetic polymer derived from methacrylamide monomers, characterized by its amide functional groups which impart unique properties. This polymer is valued for its ability to modify rheology, enhance adhesion, and act as a flocculant or thickener in various formulations. It is essential for manufacturers in the water treatment, coatings, adhesives, and specialty chemical industries seeking to improve product performance and process efficiency.

Application

• Water Treatment: Used as a flocculant and coagulant aid for clarifying process water and wastewater.
• Paper & Pulp Industry: Functions as a retention aid and drainage promoter to improve paper quality and production efficiency.
• Coatings & Paints: Serves as a rheology modifier and thickener to control viscosity and application properties.
• Adhesives & Sealants: Enhances bonding strength, cohesion, and thermal stability in industrial adhesive formulations.
• Enhanced Oil Recovery (EOR): Acts as a viscosifier in polymer flooding operations to improve oil displacement.
• Personal Care: Utilized as a film-forming agent and stabilizer in hair care and cosmetic products.
• Textile Processing: Applied as a sizing agent and finishing chemical to improve fabric handle and durability.
• Soil Conditioning: Employed in agriculture as a soil stabilizer and water retention polymer.

Quality Control

Our Polymethacrylamide is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including molecular weight distribution, residual monomer content, viscosity, and purity to ensure consistent performance and compliance with industry standards. Certificates of Analysis (COA) documenting these specifications are available upon request.

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 container must be kept tightly sealed to prevent absorption of atmospheric moisture which can affect product properties.
