CELLULOSE ACETATE BUTYRATE Usage And Synthesis
  • Chemical Propertieswhite granular crystalline powder
  • UsesContact lens material (hydrophobic).
    Cellulose acetate butyrate is the most commonly used organic cel- lulose ester for coating applications.
  • Industrial usesCommonly called butyrate or CAB, it is somewhattougher and has lower moisture absorptionand a higher softening point than acetate.CAB is made by the esterification of cellulosewith acetic acid and butyric acid in the presenseof a catalyst. It is particularly valuedfor coatings, insulating types, varnishes, andlacquers.
    Special formulations with good weatheringcharacteristics plus transparency are used foroutdoor applications such as signs, light globes,and lawn sprinklers. Clear sheets of butyrateare available for vacuum-forming applications.Other typical uses include transparent dial covers,television screen shields, tool handles, andtypewriter keys. Extruded pipe is used for electricconduits, pneumatic tubing, and low-pressurewaste lines. Cellulose acetate butyrate alsois used for cable coverings and coatings. It ismore soluble than cellulose acetate and moremiscible with gums. It forms durable and flexiblefilms. A liquid cellulose acetate butyrate isused for glossy lacquers, chemical-resistantfabric coatings, and wire-screen windows. Ittransmits ultraviolet light without yellowing orhazing and is weather-resistant.
