The family of cellulosics which are the most widely used includes cellulose acetate ellulose acetate butyrate, cellulose propionate, and ethyl cellulose. 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.
CA-Cellulose acetate, which is the lowest-cost cellulosic material, has good toughness and rigidity. This easily molded material is available in a variety of grades, ranging from"soft"to hard.
CAB-Cellulose acetate butyrate, although a little more expensive than the straight acetate, is somewhat tougher, with a hornlike quality, and has lower moisture absorption. It has relatively good
weatherability and excellent transparency.
