  • Applications

    Starch acetate (CAS 9045-28-7) is an acetylated starch derivative used as a biodegradable polymer with film-forming, binder, and carrier properties. In packaging and paper industries, it serves as a coating material and adhesive for papers and printed films, improving film strength and processability; it also functions as a film-forming or reinforcing component in starch-based plastics and coatings; it can act as a carrier or controlled-release matrix for agrochemicals and fertilizers in agriculture; and it serves as a binder and film-former in adhesives and surface coatings for textiles and paper. The applications depend on the degree of acetylation and processing conditions, and are subject to local regulations and formulation limits.
