伊士曼CAB 381-0.1Product Description
Remarkable polymers with a renewable backbone provided by nature itself.
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 is needed. It is soluble in a wide range of solvents and compatible with many other resins. 仁捷塑胶有料有限公司是美国伊士曼CAB代理商之一，CAB销售热线：18681139818 联系人：唐生 QQ:13931677。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.
