Useful:

• Uses: Contact lens material (hydrophobic). Cellulose acetate butyrate is the most commonly used organic cel- lulose ester for coating applications. Generally, an increase in butyryl content increases flexibility, moisture resistance, solubility and compatibility with resins; as the butyryl content increases, hardness, tensile strength and heat resistance decrease. Cellulose acetate-butyrate injection mouldings are particularly tough and are used for such applications as tabulator keys and tool handles; film is employed as a puncture-resistant packaging material. Cellulose acetate-butyrate is also used in lacquers for such items as cables, fabrics and furniture and in melt and strip coatings.
