Eastman CAB 500-5Product Description
Remarkable polymers with a renewable backbone provided by nature itself.
Eastman™ Cellulose Acetate Butyrate (CAB-500-5) is a cellulose ester with high butyryl content, low hydroxyl content and medium ASTM(A) viscosity. 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。CAB-500-5 offers a wide range of solubility and compatibility. It is tolerant of nonpolar aliphatic and aromatic hydrocarbons. It produces a relatively soft, flexible film requiring little or no plasticizer in many applications. Eastman™ CAB-500-5 is supplied as a dry, white free-flowing powder convenient to handle. Eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
