It is used to make plastic bases, films and various coatings with high transparency and good weather resistance as leveling agents and film-forming substances. In addition to hydroxyl and acetyl groups, the molecule of CAB [3] also contains butyryl groups, and its properties are related to the content of the three groups. The melting point and tensile strength increased with the increase of acetyl group content, and the compatibility with plasticizer and the flexibility of the film increased with the decrease of acetyl group content within a certain range. The increased hydroxyl content promotes its solubility in polar solvents. The increase of butyryl content reduces the density and enlarges the dissolution range.

Application

It has excellent moisture resistance, UV resistance, cold resistance, flexibility, transparency, electrical insulation and other properties, and has good compatibility with resins and high-boiling point plasticizers. It can be used to make film bases, aerial photography bases, Films, oil field natural gas and other transportation pipelines, tool handles, glass lamps for automobiles and airplanes, underground telephone lines and cable pipes, steering wheels, sign surfaces, flash reflectors, etc. Man-made fibers.
