EASTMAN™ CELLULOSE ACETATE BUTYRATE (CAB-381-2)
EASTMAN™ CELLULOSE ACETATE BUTYRATE (CAB-381-2) is a cellulose ester with medium butyryl content and high viscosity. Other than a higher viscosity and molecular weight, this cellulose ester shares the same general characteristics as CAB-381-0.1 and CAB-381-0.5. CAB-381-2 offers a combination of solubility and compatibility, moisture resistance, excellent surface hardness, and good film strength. When CAB-381-2 is dissolved in appropriate solvents, a clear, colorless solution is produced. It is supplied as a dry, free-flowing powder. Eastman CAB-381-2 is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 40% for Eastman CAB-381-2 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.
