Product Description
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.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™cellulose esters are based on up to sixty percent cellulose，one of the most abundant natural renewable resources.
