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. When CA-398-30 is dissolved in appropriate solvents a clear, colorless solution is produced. 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.
Eastman CA-398-30 is based on cellulose, one of the most abundant natural renewable resources.The calculated approximate bio-content value of 55% for Eastman CA-398-30 was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
