About Polyethyleneimine
Polyethyleneimine (PEI) is a synthetic polymer characterized by a high density of primary, secondary, and tertiary amine groups. Its cationic nature allows it to interact strongly with negatively charged surfaces, making it an ideal choice for flocculation, adhesion promotion, and surface modification in various industrial processes.
In the Indian market, PEI is extensively utilized in the paper and pulp industry to enhance retention and drainage, as well as in municipal and industrial water treatment plants for effective sludge dewatering and heavy metal removal. Its role as an adhesion promoter in the manufacturing of laminates and specialty coatings is also highly valued by domestic manufacturers.
When procuring PEI in India, buyers should prioritize suppliers who provide clear documentation on molecular weight distribution and active content, as these parameters dictate performance. It is recommended to source from established chemical distributors who maintain cold-chain or climate-controlled storage to ensure the stability and shelf-life of the polymer.

Is PEI suitable for drinking water treatment?
PEI is primarily used for industrial wastewater treatment; please consult local regulatory standards for potable water applications.
How does PEI improve paper production?
It acts as a retention aid by neutralizing anionic charges in the pulp slurry, improving fiber and filler retention.
What is the difference between branched and linear PEI?
Branched PEI is more common in industrial applications due to its higher reactivity and lower cost compared to linear variants.
Can PEI be used in food packaging?
Usage in food contact materials is subject to specific FSSAI and international safety regulations; verify compliance before use.
How should I store PEI to prevent degradation?
Keep in original sealed containers away from moisture and extreme heat to maintain its cationic activity.
