Producer: 
Eastman
Eastman Cellulose Acetate Butyrate (CAB-553-0.4) is soluble in low molecular weight alcohols (methanol, ethanol, isopropanol, and n-propanol) as well as other common organic solvents. It has a high hydroxyl content (4.8 wt. %, average), which contributes to its alcohol solubility. The hydroxyl group is reactive and may be crosslinked with urea formaldehydes, melamines, and polyisocyantes. When CAB-553-0.4 is dissolved in appropriate solvents a clear, colorless solution is produced. Films of CAB-553-0.4 are colorless and have good ultraviolet stability, maintaining their low color over long periods of time. Eastman Cellulose Acetate Butyrate (CAB-553-0.4) is supplied as a dry, free-flowing powder, offering formulation convenience, ease of handling and maximum formulating flexibility.Eastman CAB-553-0.4 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 41% for Eastman CAB-553-0.4 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. For applications that require food contact compliance, please refer to Eastman CAB-553-0.4, Food Contact.
