Description

2-Propenoic Acid, 2-(Dimethylamino)Ethyl Ester, Polymer With 2-Propenamide, Sulfate is a cationic polyelectrolyte copolymer, widely recognized for its flocculation and retention aid properties. This polymer is engineered to deliver superior performance in water treatment and paper manufacturing processes by effectively binding to suspended particles and fines. It is a critical raw material for industries requiring efficient solid-liquid separation, charge neutralization, and viscosity modification.

Application

• Water & Wastewater Treatment: As a primary flocculant for clarifying raw water, treating industrial effluent, and sludge dewatering.
• Paper & Pulp Industry: As a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing sheet formation and reducing BOD/COD in white water.
• Mineral Processing: For solid-liquid separation in processes like tailings dewatering and concentrate thickening.
• Textile Industry: As a fixing agent and dye retention aid to improve color fastness and reduce dye migration.
• Oilfield Applications: As a component in drilling muds and completion fluids for shale inhibition and viscosity control.
• Personal Care & Cosmetics: As a conditioning agent and thickener in hair care and skincare formulations.

Quality Control

Our production of this cationic copolymer adheres to strict quality management systems. Every batch is tested against key parameters including cationic degree, molecular weight, viscosity, and solids content to ensure consistent performance in your application. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and physical properties is provided with each shipment.

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 viscosity changes due to moisture absorption. Keep away from strong oxidizing agents.
