Producer: 
Eastman
Eastman Cellulose Acetate (CA-320S) is a cellulose ester with a high hydroxyl content. When CA-320S is dissolved in appropriate solvents, a clear, colorless solution is produced. It is supplied as pellets.Eastman CA-320S is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 63% for Eastman CA-320S 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.
