    Application
    Cellulose acetate butyrate, commonly referred to as CAB, serves as a versatile material extensively used for its film-forming and coating capabilities. The distinctive property of CAB lies in its molecular structure, where the hydroxyl groups on cellulose are partially substituted with acetyl and butyryl groups. This modification, achieved through the esterification process with acetic and butyric acids, results in a material that exhibits reduced moisture absorption, higher toughness, and an elevated softening point compared to cellulose acetate. With its excellent weathering characteristics and transparency, CAB is ideal for outdoor use, finding applications in signs, light globes, and lawn sprinklers. Its versatility extends to the production of clear sheets for vacuum forming, as well as its use in manufacturing transparent dial covers, television screen shields, tool handles, and typewriter keys. Moreover, CAB's solubility and compatibility with other compounds make it suitable for creating durable, flexible films, glossy lacquers, chemical-resistant fabric coatings, and wire-screen windows. Its inherent ability to transmit ultraviolet light without degradation enhances its appeal for applications where clarity and long-term durability are vital.
