Ethyl Cellulose

In contrast to methyl cellulose, ethyl cellulose is commonly prepared in its organic soluble state with a DS of 2.3-2.6. Films of ethyl cellulose are thermoplastic, and they resist alkali and salts. Because of their organic solubility, the films tend to swell very little in the presence of water. The resistance of ethyl cellulose to chemical degradation has led to its use in films, lacquers, and adhesives. In adhesives, ethyl cellulose may either be applied in a solvent or as a hot-melt.
