Products Description
What is Polyethyleneimine pei?
Polyethyleneimine PEI is colourless or slightly yellow high viscosity liquid. Easily soluble in water, ethanol, hygroscopic, insoluble in benzene and acetone. It will be precipitated when it meets sulfuric acid with pH value lower than 2.4. The aqueous solution is positively charged, and will be condensed by adding formaldehyde. The main use of polyethyleneimine is as a resin material, widely used in coatings, adhesives, plastic modifiers and fibre manufacturing and other fields. It has excellent adhesion, weather resistance and chemical stability, and can be used to protect and beautify the surface of objects and enhance the strength and durability of materials.
Applications of Polyethyleneimine PEI Solution ：
1. Polyethyleneimine is used as wet strength agent of non sizing breathable paper, retention agent and beating agent in the process of papermaking, which 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. Poly ethyleneimine is widely used in the fields of printing ink, coating, adhesive and so on.
3. Used in papermaking water treatment, electroplating solution and dispersant.
4. Used as epoxy resin reagent, aldehyde adsorbent and dye fixative.
