Producer: 
Eastman
Eastman Cellulose Acetate Butyrate CAB 171-15 has the lowest butyryl content and the lowest degree of solubility in the series of Eastman cellulose esters product line. It is soluble in low molecular weight ketones, chlorinated hydrocarbons, and nitroparaffins. When CAB-171-15 is dissolved in appropriate solvents a clear, colorless solution is produced.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. It is supplied in dry, powder form.Eastman CAB-171-15 is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests.The calculated approximate bio-content value of 46% for Eastman CAB 171-15 was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
