Revolutionize Your Processes with 99% Liquid Polyethyleneimine (PEI): The Versatile Performance Polymer Solution

Unlock Unmatched Versatility & Performance:

Liquid PEI stands out as a uniquely functional cationic polymer. Its branched structure and high density of amine groups (–NH₂) deliver powerful properties that solid forms struggle to match:

• Effortless Integration: Ready-to-use liquid formulation eliminates complex dissolution steps, saving valuable time and labor costs. Integrate seamlessly into existing aqueous systems.
• Superior Binding & Adhesion: Strong cationic charge promotes exceptional adhesion to negatively charged surfaces (cellulose, silica, metals, biological cells), crucial for coatings, adhesives, and composites.
• Unrivaled Flocculation & Retention: Highly effective in water treatment for clarifying process water and wastewater by agglomerating suspended solids. Boosts retention and drainage in papermaking.
• Enhanced Biocompatibility & Modification: Widely used in biotechnology for immobilizing enzymes, modifying surfaces for cell culture, gene delivery vectors (non-viral transfection), and creating functional hydrogels.
• Robust Chelation & Scale Inhibition: Binds effectively to metal ions (like Cu²⁺), aiding in corrosion inhibition and scale prevention in industrial processes.
