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。
當(dāng)纖維素酯化既乙酰基和丁酰基自由基,以形成混合酯,丁酸纖維素,其中許多都酯的期望的性質(zhì)而異。 CAB 171-15在系列伊士曼™丁酸纖維素的低丁內(nèi)容。它是在干燥,粉末形式供應(yīng),并提供作為過濾產(chǎn)品。從CAB 171-15制備的薄膜具有卓越的韌性和硬度,與其他混合酯制備的薄膜進(jìn)行比較。也基于CAB 171-15 ,其具有更少的溶解性和相容性比更高丁酰基的CAB涂料,通常提供對(duì)化學(xué)品,油和潤(rùn)滑脂優(yōu)異。 CAB 171-15呈現(xiàn)伊士曼™纖維素酯家族的溶解度低程度。它可溶于低分子量酮,氯化烴,和硝基烷。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 is made on CAB solutions using Pt-Co standards for color and a monodisperse latex suspension for haze. Analysis is performed with a Gardner Model XL-835 colorimeter. |
