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 and is convenient to handle. Eastman cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.

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).
Determination of color made on a solution of the ester dissolved in MIBK using Pt-Co color standards. Haze is based on scattered light from a monodispersed polystyrene latex suspension haze standard.
Polystyrene equivalent number average molecular weight determined by gel permeation chromatography.
