EC N22

KimaCell^® EC N22 ethyl cellulose also known as ethyl cellulose ether, or EC for short, is a non-ionic cellulose ether in the form of white or light gray powder, non-toxic and tasteless. Ethyl cellulose has the characteristics of non-combustibility, hygroscopicity, low temperature resistance, good flexibility, good thermal stability, alkali resistance, weak acid resistance, salt resistance, strong biological resistance, and good dielectric properties.

Ethyl cellulose is prepared from wood pulp and cotton linters, which are alkalized with sodium hydroxide to produce alkali cellulose, then etherified with ethyl chloride, and finally washed and dried. During the preparation process of ethyl cellulose, the degree of etherification directly affects its physical and chemical properties. For example, if the degree of etherification is high, its hygroscopicity will decrease, its solubility in alkali will decrease, and its solubility in organic solvent will increase. In addition, its thermal Stability and mechanical properties will also change. Manufacturers need to reasonably control the degree of etherification to ensure the quality of ethyl cellulose products, and can also produce products with different characteristics according to the downstream market demand.
