General description

Cellulose acetate (CA) is a class of cellulose based esters which can be produced by a reaction of cellulose with acetic acid and acetic anhydride. It can be used in a variety of forms such as films, membranes, and fibers. It can be used as a biodegradable polymer in medical and automotive applications.

Application

CA can be used as a material in packaging, clothing and pharmaceuticals industries. It can also be used in the formation of polymeric electrolyte for the fabrication of electrochemical devices like fuel cells, solar cells and supercapacitors.

Features and Benefits

  • High purity grade , biodegradable suitable for demanding industrial and research applications.
  • High Molecular weight for enhanced strength, film forming properties and adhesion
  • Offered in powder form easy to handle, measure, and dissolve.
  • Low moisture content ensures stability and prevents hydrolysis during storage and processing.
  • The refractive index makes it suitable for lenses, coatings, and display technologies.
