Product Description

Remarkable polymers with a renewable backbone provided by nature itself.

Eastman™ Cellulose Acetate Butyrate (CAB-551-0.01) is a cellulose ester with high butyryl content and low ASTM(A) viscosity, which significantly affects it solubility and compatibility. Eastman™ CAB-551-0.01 is soluble in styrene and methyl methacrylate monomers and will tolerate more aliphatic and aromatic hydrocarbon diluent than higher viscosity materials. The solubility of CAB-551-0.01 in alcohol/aromatic hydrocarbon mixtures offers an economic advantage and permits the choice of a wide range of solvents and solvent combinations. It also offers improved compatibility with various coating resins. Eastman™ CAB-551-0.01 is a dry, white free-flowing powder convenient to handle. Eastman™ cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources.
