The family of cellulosics includes cellulose acetate, cellulose acetate butyrate, cellulose propionate, and ethyl cellulose. There are other cellulosics, but these are the most widely used. Cellulosics are characterized by good strength, toughness, and transparency and high surface gloss. The main feature of cellulosics is their excellent moldability, which results in brilliant, high-gloss finish. Cellulosic compounds are available for extrusion, injection molding, blow molding, and rotational molding, Cellulosics also are widely used in the form of film and sheet.
