Purity: 98%
Appearance:White or light yellow crystalline powder.
Packing: aluminum foil bag/bottle, 25kg/drum or as your request
Uses: PEI and its derivatives are used as flocculants, heavy metal adsorbents and surfactants in the field of water treatment and gas purification.

It can be used as a synergist and filter promoter in paper industry.

It is used as wet strength agent, anti-static treatment, flame retardant processing, shrink-proof, dyeing improvement and so on in the fiber industry.

Applied to coatings, inks, binders (including hot-welded plastic seals) can promote bonding, creep resistance, improve the dispersion of pigments and fillers, anti-agglomeration, improve the stability of coatings, etc.

Applying to cosmetics can improve hair quality, anti-bacterial and soft skin.

In oil exploitation and deep well operation, fluid loss, viscosity reduction, paraffin deposition prevention and clay stability can be prevented.

It can improve the compatibility between artificial organs and blood, and also be used as a coating for medical devices.

In addition, it is also the composition of ion exchange resin and exchange membrane, resin crosslinking agent, crystallization additive, electroplating gloss agent, metal rust inhibitor, gasoline and diesel fuel additive, lubricating oil additive, glass cleaning agent, liquid chromatography stationary phase, polymer catalyst, etc. It is also used in the study of synthetic enzyme model.
