Description

Poly(3-Chloro-2-Hydroxypropyl-2-Methacryloxyethyldimethylammonium Chloride) is a high-performance, water-soluble cationic polymer widely used as a flocculant and retention aid. Its unique structure provides strong charge density and bridging capabilities, making it essential for solid-liquid separation processes. This polymer is a critical raw material for water treatment, paper manufacturing, and mineral processing industries seeking to improve efficiency and meet environmental discharge standards.

Application

• Water & Wastewater Treatment: Primary application as a high-efficiency cationic flocculant for clarifying industrial and municipal wastewater, sludge dewatering, and potable water treatment.
• Paper & Pulp Industry: Acts as a powerful retention and drainage aid, improving fiber and filler retention, sheet formation, and water removal on the paper machine wire.
• Mineral Processing: Used in the beneficiation of ores (e.g., coal, iron, potash) for solid-liquid separation, tailings management, and concentrate dewatering.
• Oilfield Chemicals: Employed in drilling muds and produced water treatment as a viscosifier and clarifier.
• Textile Industry: Serves as a dye-fixing agent and wastewater coagulant in textile mill operations.
• Personal Care: Utilized as a conditioning agent and viscosity modifier in hair care and skincare formulations.

Quality Control

Our production of Poly(3-Chloro-2-Hydroxypropyl-2-Methacryloxyethyldimethylammonium Chloride) adheres to stringent quality management protocols. Every batch undergoes rigorous testing for critical parameters including cationic charge density, molecular weight distribution, viscosity, and residual monomer content to ensure consistent performance. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance and regulatory compliance needs.

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); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
