Description

Poly(2-Methacryloxyethyltrimethylammonium Bromide) is a high-purity, cationic polyelectrolyte widely used as a flocculant and retention aid in water treatment and paper manufacturing. Its quaternary ammonium groups provide strong positive charges, making it highly effective for binding and neutralizing negatively charged particles and colloids. This polymer is essential for industries requiring efficient solid-liquid separation, including municipal and industrial wastewater treatment, mining, and the production of high-quality paper and board.

Application

• Water & Wastewater Treatment: Primary application as a high-performance cationic flocculant for clarifying process water, treating industrial effluent, and sludge dewatering.
• Paper & Pulp Industry: Key retention and drainage aid to improve fiber and filler retention, enhance paper formation, and increase production efficiency.
• Mining & Mineral Processing: Used for tailings dewatering, thickening, and clarification to recover process water and reduce environmental impact.
• Oilfield & Petroleum: Functions as a viscosity modifier and clay stabilizer in drilling fluids and as a component in enhanced oil recovery formulations.
• Textile & Dyeing: Acts as a dye fixative and flocculant for treating colored wastewater from dye houses.
• Cosmetics & Personal Care: Utilized as a conditioning agent and viscosity enhancer in hair care and skincare formulations.
• Biotechnology & Research: Serves as a cationic coating material for surface modification, cell adhesion studies, and in DNA complexation.

Quality Control

Our Poly(2-Methacryloxyethyltrimethylammonium Bromide) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of cationic charge density, molecular weight distribution, and purity. A comprehensive Certificate of Analysis (COA) detailing assay, viscosity, and residual monomer content is provided with every shipment to guarantee compliance with your technical 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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
