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%.

1. Polyethyleneimine PEI used as wet strength agent of non sizing breathable paper, retention agent and beating agent in the process of papermaking, PEI 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%.
2. Polyethyleneimine solution widely used in the fields of printing ink, coating, adhesive and so on.
3. PEI used in papermaking water treatment, electroplating solution and dispersant.
4. Polyethyleneimine used as epoxy resin reagent, aldehyde adsorbent and dye fixative.
1. Application Highlights
Papermaking Whitewater Purification: Replaces traditional aluminum salts, improves water clarity, and reduces COD.
Electroplating Wastewater Treatment: Captures Cu²⁺, Ni²⁺, and Cr⁶⁺ in one go, ensuring discharge meets standards.
Dye Wastewater: Decolorization rate >95%, reducing operating costs by 30%.
2. PEI offers a wide molecular weight range of 500–750,000 and can be acetylated, carboxylated, PEGylated, and fluorescently labeled to achieve on-demand design of water-solubility, oil-solubility, and targeting.
3. Comparable to BASF, Catalyst and other brands. The same specifications have more competitive prices.
4. Provide one-to-one technical knowledge. Lock in specific specifications according to customer product applications.
