產(chǎn)品描述
由自然本身提供一種可再生的骨干了不起的聚合物。
伊士曼™醋酸丁酸纖維素(CAB381-0.1)是一種纖維素酯具有中等丁?;亢偷驼扯?。它被設(shè)計(jì)用于那些需要低粘度應(yīng)用在相對(duì)較高的固體含量。它可溶于寬范圍的溶劑和與許多其他樹(shù)脂相容的。它也將容忍使用溶劑混合物當(dāng)前豁免于某些空氣污染法規(guī)。它是提供一個(gè)干燥,自由流動(dòng)的粉末。伊士曼™纖維素酯是基于高達(dá)60%的纖維素,豐富的天然可再生資源之一。

a 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). b Determination of color and haze made on a solution of the cellulose ester dissolved in MIBK using Pt-Co color standards and Johns-Manville Celite (diatomaceous silica products) haze standards. c Polystyrene equivalent number average molecular weight determined by gel permeation chromatography. |
