Product Description
|
Remarkable polymers with a renewable backbone provided by nature itself.
Eastman? CAB-381-2 is a cellulose ester with high butyryl content and high ASTM(A) viscosity. Other than a higher viscosity and molecular weight, this cellulose ester shares the same general characteristics as CAB-381-0.1 and CAB-381-0.5. CAB-381-2 offers a combination of solubility and compatibility, moisture resistance, excellent surface hardness, and good film strength. It is supplied as a dry, free-flowing powder. Eastman? cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.

產(chǎn)品描述
|
非凡的聚合物可再生自然本身提供的骨干。
伊士曼鈩?出租車(chē)- 381 - 2是纖維素酯和丁酰內(nèi)容和ASTM(a)高粘度。除了更高的粘度和分子量,纖維素酯共享相同的一般特征為出租車(chē)- 381 - 0.1和出租車(chē)- 381 - 0.5。出租車(chē)- 381 - 2提供了一個(gè)組合的溶解性和兼容性,防潮性,優(yōu)良的表面硬度,和良好的膜強(qiáng)度。它提供干燥、自由流動(dòng)粉末。伊士曼鈩?纖維素酯類(lèi)是基于纖維素百分之六十,其中最豐富的天然可再生資源。
