POLYETHYLENEIMINE (PEI), cas number 9002-98-6, is an important synthetic polymer material with a variety of special properties and a wide range of applications. It is a linear polymer that is synthesized from ethylene imide monomer by polymerization. POLYETHYLENEIMINE has high molecular weight, high branching, abundant amine groups, etc., which makes it have a wide application prospect in the field of electronics, opto-electronics, and aviation.

POLYETHYLENEIMINE is a polymer with good solubility that dissolves in a variety of solvents. It has a high solubility in water and can form a stable colloidal solution with water. This dissolution property makes PEI have good processability and controllability, and can be prepared by solution method, thermoforming, spraying and other methods of different shapes and sizes of materials.


What are the characteristics of POLYETHYLENEIMINE?

1. Waterproof: POLYETHYLENEIMINE has good waterproof performance, which can effectively prevent water penetration and leakage.

2. Heat insulation: POLYETHYLENEIMINE has good heat insulation performance and can effectively prevent the transfer of heat energy.

3. Freshness/POLYETHYLENEIMINE has strong airtight performance, which can effectively maintain the freshness of food and other items and extend the shelf life.

4. Corrosion resistance: POLYETHYLENEIMINE has high corrosion resistance and is able to resist the attack of certain chemicals.

5. High strength: POLYETHYLENEIMINE has high strength and is able to effectively resist pull, pull, squeeze and other forces.
