Cyanoethyl cellulose (CEC) is widely used in the production of specialty papers, where it enhances strength, durability, and water resistance. It is also employed as a thickening agent in various industrial applications, including coatings and adhesives, due to its ability to modify viscosity and improve stability. In the textile industry, CEC is utilized as a sizing agent to improve the handling and processing of fibers. Additionally, it finds application in the development of advanced materials, such as films and membranes, where its unique properties contribute to enhanced performance. Its compatibility with other polymers makes it a valuable component in composite materials for electronics and packaging.
