Eastman Cellulose Acetate (CA-398-6) is a low viscosity solution grade cellulose acetate. When dissolved in appropriate solvents selected for CA-398-6, a clear, colorless solution is produced. Eastman CA-398-6 is supplied in the form of fine, dry, free-flowing powder.
Eastman CA-398-6 is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests.The calculated approximate bio-content value of 55% for Eastman CA-398-6 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.
