Product Description
Eastman™ Cellulose Acetate CA-398-30 is a high-viscosity, high molecular weight cellulose acetate supplied as fine, dry, free-flowing powder. The powder is free from coarse particles and excessive fines. Its relatively uniform particle size permits good plasticizer distribution during blending. Cellulose acetate CA-398-30 offers good physical properties for molded and extruded articles. It may be compounded into plastic using extrusion equipment or heated rolls.

aDetermination 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.
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).
