• Application: Cellulose acetate butyrate serves as a versatile material known for its durability, transparency, and flexibility. It is a cellulose ester with hydroxyl groups on glycoside rings partially or fully replaced by acetyl and butyryl groups, which can vary in ratio to tailor its properties. This adaptability makes it ideal for a wide range of applications, from coatings and varnishes to electrical conduits and outdoor signage. Its ability to transmit ultraviolet light without yellowing or hazing, combined with its resistance to weather, enhances its functionality in both indoor and outdoor settings. Additionally, its hydrophobic nature makes it an excellent choice for contact lens materials, balancing toughness with a high softening point for reliable performance.
