Polyethyleneimine (PEI), identified by CAS number 9002-98-6, is a polymer available in a wide range of molecular weights, from as low as 600 to as high as 20,000,000. NINGBO INNO PHARMCHEM CO.,LTD. provides this versatile chemical, catering to diverse industrial needs that leverage its unique properties across different molecular weight distributions.

The varying molecular weights of PEI significantly influence its physical and chemical characteristics, such as viscosity, solubility, and reactivity. For instance, lower molecular weight PEI might be preferred for applications requiring higher fluidity, like in certain coating or ink formulations, while higher molecular weight PEI can offer enhanced film-forming properties or stronger binding capabilities, beneficial in applications like papermaking as a wet strength agent or in advanced adhesives.

In the papermaking industry, PEI is widely utilized as a wet strength agent and a retention aid. The specific molecular weight chosen can optimize its performance, affecting how effectively it binds to cellulose fibers and improves the paper's resistance to moisture. This broad applicability showcases the importance of understanding the nuances of polyethyleneimine industrial applications based on molecular weight.

Beyond papermaking, PEI's utility extends to numerous other sectors. It is employed in printing inks and coatings, acts as a chemical auxiliary and catalyst, and is used in water treatment processes. Its role as an epoxy resin reagent and an aldehyde adsorbent further highlights its versatility. The selection of the appropriate PEI molecular weight is often critical for achieving the desired performance in these varied applications, whether it's for enhancing adhesion, improving catalytic activity, or facilitating water purification.
