product description
remarkable polymers with a renewable backbone provided by nature itself.
when cellulose is esterified with both acetyl and butyryl radicals to form the mixed ester, cellulose acetate butyrate, many of the desirable properties of both esters are obtained. cab 171-15 has the lowest butyryl content in the series of eastman™ cellulose acetate butyrates. it is supplied in dry, powder form and is offered as a filtered product. films prepared from cab 171-15 offer superior toughness and hardness as compared with films prepared from other mixed esters. also coatings based on cab 171-15, which has less solubility and compatibility than the higher butyryl cabs, usually offer excellent resistance to chemicals, oils, and greases. cab 171-15 exhibits the lowest degree of solubility of the eastman™ cellulose ester family. it is soluble in low molecular weight ketones, chlorinated hydrocarbons, and nitroparaffins. eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
