Usage

General Description

Polyethyleneimine (PEI) is a polymer with a high molecular weight and a branched structure. It is commonly used in various industrial and commercial applications due to its adhesive, flocculating, and film-forming properties, as well as its ability to act as a cationic polyelectrolyte. PEI is frequently employed as a dispersing agent, a binder in paper production, and a flocculant in wastewater treatment processes. It is also utilized in the production of adhesives, coatings, and textiles, as well as in the formulation of personal care products and pharmaceuticals. Additionally, PEI is a valuable material in the field of biomedical engineering, where it is utilized in gene and drug delivery systems, tissue engineering, and medical diagnostic applications. Despite its widespread use, PEI can cause irritation to the skin, eyes, and respiratory system, and therefore proper safety precautions should be taken when handling this chemical.
