伊士曼CAB 381-20BPProduct Description
Remarkable polymers with a renewable backbone provided by nature itself.
Eastman™ Cellulose Acetate Butyrate (CAB-381-20BP), 100% grade ester is a slight modification of the standard CAB-381-20 cellulose acetate butyrate and has a lower 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。The BP grade was designed primarily to meet the needs of European formulators. Eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.

| a Determination of color and haze is made on CAB solution using Pt-Co color standards (color) and a monodisperse latex suspension (haze). Analysis is performed with a Gardner Model XL-835 colorimeter. b Polystyrene equivalent number average molecular weight determined by gel permeation chromatography. c Viscosity determined by ASTM Method D 1343. Results converted to poises (ASTM Method D 1343) using the solution density for Formula A as stated in ASTM Method D 817 (20% Cellulose ester, 72% acetone, 8% ethyl alcohol). |
