Description

2-Propenoic acid, ethyl ester, polymer with diethenylbenzene, 2-ethenylpyridine and methyl 2-propenoate, reaction products with N-(3-aminopropyl)-N-methyl-1,3-propanediamine and N,N-dimethyl-1,3-propanediamine, chloromethane-quaternized is a specialized, high-performance cationic polymer designed for demanding industrial applications. This quaternized copolymer is engineered to provide exceptional performance as a flocculant, retention aid, and charge neutralization agent in complex aqueous systems. It is a critical material for industries requiring advanced water treatment, paper manufacturing, and mineral processing solutions where controlling colloidal stability and enhancing separation efficiency are paramount.

Application

• Industrial Water & Wastewater Treatment: Primary application as a high-efficiency cationic flocculant for the clarification and dewatering of municipal and industrial sludge.
• Paper & Pulp Manufacturing: Functions as a superior retention and drainage aid, improving fiber and filler retention on the paper machine wire for enhanced productivity and quality.
• Mineral Processing: Used in the beneficiation of ores (e.g., iron ore, potash, coal) for solid-liquid separation, tailings management, and concentrate dewatering.
• Oilfield & Petroleum Industry: Applied in drilling muds and produced water treatment for viscosity control, shale inhibition, and oil-water separation.
• Textile Processing: Acts as a dye-fixing agent and coagulant for treating dyehouse effluent, improving color removal and reducing chemical oxygen demand (COD).
• Sugar Refining: Aids in the clarification process by flocculating impurities from cane or beet juice, improving filtration rates and sugar yield.

Quality Control

Our production of this cationic polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as cationic charge density, molecular weight distribution, viscosity, and solids content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

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 / 59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
