Product Description
Eastman™ Cellulose Acetate (CA-398-6) is a low viscosity solution grade cellulose acetate. Eastman™ cellulose acetate is supplied in the form of fine, dry, free-flowing powder. Food additive regulations issued by the Food and Drug Administration (FDA) permit use of cellulose acetate in specific food packaging applications. Cellulose acetate is also prior sanctioned for use in film in food-contact applications. CA is also recognized by the FDA as generally recognized as safe (GRAS) for use in paper and paperboard in contact with food.

aDetermination of color and haze is made on CAB solutions using Pt-Co standards for color and a monodisperse latex suspension for haze according to ASTM Method D 871 and Eastman Test Method TECE-A-CL-G-VIS-16-1 with a Gardner Model XL-835 colorimeter.
bViscosity 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).
