Description and Uses

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.
