Description

Polyethylenimin, Polymer With Ethylene Oxide And Propylene Oxide is a versatile, water-soluble cationic polymer derived from the modification of polyethylenimine. This engineered copolymer is valued for its unique combination of cationic charge density and tunable hydrophilicity, making it an effective agent for binding, flocculation, and surface modification. It serves as a critical functional additive in demanding industrial processes, including water treatment, paper manufacturing, and as a component in specialty coatings and adhesives.

Application

• Water Treatment: Acts as a highly effective flocculant and coagulant aid for the removal of suspended solids, organic matter, and colorants in industrial and municipal wastewater.
• Paper Industry: Used as a retention and drainage aid, as well as a strength additive, to improve paper quality and production efficiency.
• Coatings and Adhesives: Functions as a dispersant, viscosity modifier, and adhesion promoter in the formulation of paints, inks, and adhesive systems.
• Personal Care: Employed as a conditioning agent and film-former in hair care and skincare products due to its cationic nature.
• Textile Processing: Serves as a dye-fixing agent and antistatic agent to enhance color fastness and processing performance of fabrics.
• Oil & Gas: Utilized in drilling mud formulations and as a demulsifier in crude oil processing.
