Eastman Cellulose Acetate Butyrate (CAB-381-0.5, Food Contact) 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 is needed. It is soluble in a wide range of solvents and compatible with many other resins. When CAB-381-0.5, Food Contact is dissolved in appropriate solvents, a clear, colorless solution is produced. It will also tolerate the use of solvent blends currently exempt from certain air pollution regulations. It is supplied as a dry, free-flowing powder.
Eastman CAB-381-0.5, Food Contact is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 40% for Eastman CAB-381-0.5, Food Contact 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.
