产品描述
| 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. |
