Eastman Cellulose Acetate Butyrate (CAB-381-0.1) is a cellulose ester with medium butyryl content and low viscosity. It was designed for use where low-application viscosities at relatively high solids levels are needed. It is soluble in a wide range of solvents and compatible with many other resins. It will also tolerate the use of solvent blends currently exempt from certain air pollution regulations. When CAB-381-0.1 is dissolved in appropriate solvents a clear, colorless solution is produced. It is supplied as a dry, free-flowing powder.Eastman CAB-381-0.1 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 41% for Eastman CAB-381-0.1 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.For applications that require food contact compliance, please refer to CAB-381-0.1, Food Contact.
