Eastman CAB 531-1Product Description
Remarkable polymers with a renewable backbone provided by nature itself. 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。
Eastman™ Cellulose Acetate Butyrate (CAB-531-1) is a cellulose ester with a higher butyryl level than Eastman™ CAB-381 type esters. Tough films with good resistance to marring and weathering are possible through combinations of cellulose acetate butyrate with thermoplastic acrylic resins. Eastman™ CAB-531-1 and CAB-381 esters are similar in hydroxyl content and solubility characteristics, both being soluble in a wide range of solvents. Eastman™ CAB-531-1 is a more flexible resin requiring lower plasticizer modification than the Eastman™ CAB-381 esters. Eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
