Polyethylenimine | 9002-98-6

Description :

Overview of Polyethylenimine

Polyethylenimine (PEI) is an extremely versatile polymer that is widely used in adhesives, water treatment papers, coatings, and biotechnology applications. The polymer is a branched or linear polymer that is composed of ethyleneimine units that repeat and contain primary, secondary, and tertiary amine groups.

Polyethylenimine is available in liquid and polyethylenimine powder forms, depending on the application.

Applications of Polyethylenimine

Water Treatment & Flocculation

Polyethylenimine is widely used in water and wastewater treatment as a flocculant and coagulant aid. Its cationic properties help neutralize negatively charged particles and improve sedimentation efficiency.

It may be used in combination with Polyaluminium Chloride and Polyacrylamide in water purification systems.

Paper & Pulp Industry

In paper manufacturing, Polyethylenimine is used as a wet-strength agent and retention aid. It improves fiber bonding, paper strength, and retention of fillers and pigments.

Adhesives, Coatings & Surface Treatment

Polyethylenimine is applied in adhesives and coatings to enhance adhesion, surface bonding, and chemical resistance. It also serves as a crosslinking agent in specialty coating formulations.

Biotechnology & Research Applications

Polyethylenimine is commonly used in biotechnology for gene delivery and transfection processes. Its ability to bind nucleic acids makes it valuable in laboratory and pharmaceutical research.

Safety & Handling Guidelines

• Store in tightly sealed containers in a cool, dry place
• Avoid inhalation of dust or vapors
• Use protective gloves, goggles, and appropriate protective clothing
• Handle in well-ventilated areas
• Dispose of waste according to environmental regulations

Regarding polyethylenimine toxicity, the compound can cause irritation to the skin, eyes, and respiratory system. Proper safety precautions should be followed during handling. Always consult the official MSDS before use.
