Description

1,2-Ethanediamine, n-(2-Aminoethyl)-, Polymer With (Chloromethyl)Oxirane is a polyamine-epichlorohydrin resin, a versatile cationic polymer widely used as a flocculant and retention aid. This compound is valued for its high charge density and effectiveness in binding negatively charged particles in aqueous systems. It is a critical raw material for water treatment, paper manufacturing, and various industrial processes requiring efficient solid-liquid separation.

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: Functions as a highly effective retention and drainage aid, improving fiber and filler retention on the paper machine wire and enhancing water removal.
• Mineral Processing: Used in the beneficiation of ores (e.g., iron ore, potash) for solid-liquid separation and tailings management.
• Textile Industry: Serves as a fixing agent and dye retention aid, improving color fastness and reducing dye effluent.
• Oil & Gas Industry: Applied in drilling muds and produced water treatment to control solids and clarify water.
• Sugar Refining: Acts as a flocculant in juice clarification processes to remove impurities.
