Description

Styrene/Acrylamide Copolymer is a synthetic polymer formed from the copolymerization of styrene and acrylamide monomers. This versatile material is valued for its ability to modify rheology, act as a thickening agent, and provide film-forming properties in aqueous systems. It is essential for formulators and manufacturers in industries such as water treatment, coatings, adhesives, and personal care, where performance and stability are critical.

Application

• Water Treatment Chemicals: Used as a flocculant aid and sludge dewatering agent in municipal and industrial wastewater treatment processes.
• Paper & Pulp Industry: Functions as a retention aid, drainage aid, and dry strength additive to improve paper quality and production efficiency.
• Coatings & Paints: Acts as a rheology modifier and thickener in latex paints and other water-based coating formulations to control viscosity and application properties.
• Adhesives & Sealants: Serves as a binder and thickening component in water-based adhesive systems.
• Personal Care Products: Utilized as a film former, thickener, and stabilizer in hair care, skincare, and cosmetic formulations.
• Textile Processing: Applied as a sizing agent, finishing agent, or thickener in textile printing and dyeing operations.
• Enhanced Oil Recovery (EOR): Employed in polymer flooding operations to increase the viscosity of injected water for improved oil displacement.

Quality Control

Our Styrene/Acrylamide Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, residual monomer content, and functional performance. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and physical parameters is provided with every shipment to guarantee compliance with your specifications.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
