Cellulose Acetate Butyrate (CAB-553-0.4) is a dry, free-flowing powder soluble in low molecular weight alcohols and common organic solvents. It has a high hydroxyl content (4.8 wt. %) and forms clear, colorless solutions. CAB-553-0.4 produces colorless films with good UV stability, maintaining low color over time. It is widely used in automotive OEM coatings, coatings for automotive plastics, plastic coatings, lacquers for automotive, paper, wood, nail care, printing inks, and coatings for trucks, buses, and commercial vehicles.
Our production base was founded in September 2014 with a registered capital of 50 millions Chinese Yuan, occupying an area of 54,500 square meters, certificates of lS09001, ISO14001, lS045001, EU REACH registration certificate. Our Cellulose Acetate Butyrate CAB-381 and CAB-551 annual capacity is 10000 tons and Cellulose Acetate CA 6000 tons.

CAB-553-0.4Viscosity :
1.14 poiseAppearance :
dry, free-flowing powderCellulose Acetate Butyrate (CAB-553-0.4) is supplied as a dry, free-flowing powder, offering formulation convenience, ease of handling and maximum formulating flexibility.It is soluble in low molecular weight alcohols, such as methanol, ethanol, isopropanol, and n-propanol, as well as in other common organic solvents. Its high hydroxyl content, averaging 4.8 wt.%, contributes significantly to its solubility in alcohols. The hydroxyl group is reactive and can undergo crosslinking with urea-formaldehydes, melamines, and polyisocyanates, offering enhanced versatility in formulation.
When dissolved in suitable solvents, CAB-553-0.4 forms a clear, colorless solution. Films produced from CAB-553-0.4 are also colorless and exhibit excellent ultraviolet stability, retaining their low color for extended periods. This makes it an ideal choice for applications requiring long-term clarity and stability under light exposure.
Our CAB-553-0.4 is widely used in various applications, including automotive OEM coatings, coatings for automotive plastics, general coatings, plastic coatings, lacquers for automotive, paper, and wood, as well as nail care products, printing inks, and coatings for trucks, buses, and commercial vehicles.
