Product Overview
Branched Polyethylenimine, Mw ~2,000 (bPEI 2000) is a colorless to yellowish liquid. It is a water soluble polyamine with high cationic charge density. bPEI 2000 contains primary, secondary, and tertiary amine groups in approximately 40/36/24 ratio.
Industrially, branched polyethylenimine (bPEI) because of their high charge density adsorb strongly on negatively charged surfaces such as cellulose, polyester, polyamides, metals, etc. bPEIs have extensive applications as an auxiliary agent intensifying manufacturing processes and improving quality of the final products. They are widely used in: paper-making, water treatment, detergents, adhesives, and cosmetics.
Resin Content (wt%): ≥ 99Charge Density (cationic): 16 meq/g
