When cellulose is esterified with both acetyl and butyryl radicals to form the mixed ester, cellulose acetate butyrate, many of the desirable properties of both esters are obtained. CAB 171-15 has the lowest butyryl content in the series of Eastman™ Cellulose Acetate Butyrates. It is supplied in dry, powder form and is offered as a filtered product. Films prepared from CAB 171-15 offer superior toughness and hardness as compared with films prepared from other mixed esters. Also coatings based on CAB 171-15, which has less solubility and compatibility than the higher butyryl CABs, usually offer excellent resistance to chemicals, oils, and greases. CAB 171-15 exhibits the lowest degree of solubility of the Eastman™ cellulose ester family. It is soluble in low molecular weight ketones, chlorinated hydrocarbons, and nitroparaffins. Eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.

a  Viscosity determined by ASTM Method D 1343. Results converted to poises (ASTM Method D 1343) using the solution density for Formula A as stated in ASTM Method D 817 (20% Cellulose ester, 72% acetone, 8% ethyl alcohol).
b  Determination of color and haze is made on CAB solutions using Pt-Co standards for color and a monodisperse latex suspension for haze. Analysis is performed with a Gardner Model XL-835 colorimeter.
