product description
remarkable polymers with a renewable backbone provided by nature itself. 
eastman™ cellulose acetate butyrate (cab 381-0.5) 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. 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™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
