Description

2-Propenamide, Polymer With Ethenylbenzene, Reaction Products With Formaldehyde, Dimethylamine-Modified is a specialized cationic polymer, specifically a modified polyacrylamide-styrene copolymer. This product is engineered to deliver superior performance as a flocculant and retention aid in demanding industrial water treatment and papermaking processes. It is a critical material for operations requiring efficient solid-liquid separation, charge neutralization, and process water clarification. Key industries that rely on this advanced polymer include pulp & paper manufacturing, mineral processing, and municipal/industrial wastewater treatment.

Application

• Primary Flocculant in municipal and industrial wastewater treatment for sludge dewatering and clarification.
• Retention and Drainage Aid in paper manufacturing to improve fiber and filler retention on the wire, enhancing paper quality and machine efficiency.
• Process Water Clarification in mineral beneficiation (e.g., coal, iron ore) to settle fine particles and recover process water.
• Charge Neutralization Agent for treating colloidal suspensions with a negative surface charge.
• Coagulant Aid used in conjunction with primary inorganic coagulants to form larger, faster-settling flocs.
• Binder and Strengthening Agent in non-woven fabrics, textiles, and certain construction materials.

Quality Control

Every batch of our cationic copolymer is produced under a strict quality management system. We perform comprehensive in-process and final product testing to ensure consistent performance, including analysis of cationic charge density, molecular weight distribution, viscosity, and solids content. Certificates of Analysis (COA) documenting key specifications are available for all shipments. Our manufacturing and quality processes are designed to support compliance with relevant industry and environmental standards.

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); ensure containers are sealed immediately after use to prevent caking or degradation due to atmospheric moisture. Keep away from strong oxidizing agents.
