Molecular Formula: (C6H7O2(OC2H5))n
Product Type: Cellulose Ether / Polymer Material
Common Specification: Ethoxyl Content 48.0–49.5%
Ethyl cellulose (CAS 9004-57-3) is a non-ionic cellulose derivative obtained by etherification of natural cellulose. It is insoluble in water but soluble in many organic solvents, possessing excellent film-forming properties, thermal stability, chemical resistance, and mechanical strength.
Ethyl cellulose is widely used in sustained-release pharmaceutical formulations, coatings and inks, electronic materials, food packaging, personal care products, and industrial adhesives. It is an important functional material in high-end industrial and pharmaceutical industries.
