Eastman Cellulose Acetate Butyrate (CAB-500-5) is a cellulose ester with high butyryl content, low hydroxyl content and medium ASTM(A) viscosity. It offers a wide range of solubility and compatibility. It is tolerant of nonpolar aliphatic and aromatic hydrocarbons. It produces a relatively soft, flexible film requiring little or no plasticizer in many applications. Eastman CAB-500-5 is supplied as a dry, white free-flowing powder convenient to handle. Eastman cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
