What Is Polyethyleneimine CAS 9002-98-6?
Polyethyleneimine CAS 9002-98-6 is a colorless or yellowish high viscous liquid. Soluble in water, ethanol, hygroscopic, insoluble in benzene and acetone. Precipitation will occur when it meets sulfuric acid with a pH value lower than 2.4. The aqueous solution is positively charged, and the addition of formaldehyde produces condensation. Chemicalbook 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%.
