Polyethyleneimine (PEI) is a cationic polymer with primary, secondary and tertiary amino groups separated by an ethylene bridge. PEI is available in both linear and branched forms, and there are a variety of specifications for customers to choose from based on molecular weight and viscosity.

PEI plays an important role in many fields.

Here’s how PEI can enhance your products:

- Biocompatible Coatings:Utilize PEI as a polyelectrolyte multilayer on charged surfaces to create a biocompatible coating that ensures optimal performance in biomedical applications.

- Detergents & Adhesives: Enhance the efficacy of your formulations with PEI’s properties as a stability enhancer and adhesion promoter, ensuring superior bonding and cleaning capabilities.

- Water Treatment & Flocculants: Improve water quality with PEI’s effectiveness as a flocculant, helping to remove impurities and enhance the clarity of water.

- Cosmetics & Personal Care: Incorporate PEI into your cosmetic formulations for its excellent film-forming properties, providing long-lasting effects and improved texture.

- Printing Inks & Dyes: Achieve vibrant colors and improved stability in your inks and dyes with PEI’s cationic dispersant properties.

- Paper Industry: Utilize PEI as a fixative agent and surface activator to enhance the quality and durability of paper products.
