Cellulose acetate butyrate(CAS: 9004-36-8)

Cellulose acetate butyrate (CAB) is a cellulose derivative with a high degree of acetylation and butyrylation. Its chemical formula is (C6H7O2OOCCH3)3OOCCH2CH(CH3)CO2CH3. CAB is known for its excellent mechanical properties, transparency, and flexibility, making it suitable for various applications in industry and pharmaceuticals.

Cellulose acetate butyrate (CAB) is widely used in pharmaceuticals as a tablet and capsule coating due to its flexibility and good barrier properties. It is also used in electronics for tapes and films, and in the automotive industry for coatings and adhesives. CAB is also employed in the production of optical lenses and as a component in some paints and varnishes.

Cellulose acetate butyrate (CAB) is generally considered safe for industrial and pharmaceutical use. However, it is important to handle it with proper personal protective equipment (PPE) such as gloves and goggles to avoid skin and eye irritation. Storage should be in a cool, dry place away from heat and direct sunlight. Follow all safety guidelines provided by the manufacturer.

Cellulose acetate butyrate (CAB) should be stored in a cool, dry place with a temperature range of 15-25°C (59-77°F) and relative humidity below 60%. It should be kept away from heat, direct sunlight, and sources of ignition to prevent degradation. Use appropriate containers with tight-fitting lids to maintain product integrity and prevent moisture absorption.
