Polyethyleneimine CAS 9002-98-6 with NW 600-20000000
Polyethyleneimine (abbreviated as PEI) is a colorless or yellowish high viscous liquid. CAS number 9002-98-6. Soluble in water, ethanol, hygroscopic, insoluble in benzene and acetone. Precipitation will occur when polyethyleneimine solution meets sulfuric acid with a pH value lower than 2.4. The aqueous solution is positively charged, and the addition of formaldehyde produces condensation. Polyethyleneimine PEI is used as the wet strength agent of non sized breathing paper, and the retention agent and beating agent in the process of papermaking can reduce the beating degree of pulp. Improve the dewatering capacity of paper. The dryness of the paper is increased by 1% - 4%. The production capacity is increased by 5% - 20%.
