Cellulose Acetate Butyrate (CAB) resin is a type of modified cellulose ester. It contains butyryl groups (in medium to high amounts available) and comes in different viscosity levels (low to high available). This makes it more durable, weather-resistant, and less absorbent to moisture than regular cellulose acetate. iSuoChem® offers Cellulose Acetate Butyrate with different grades, such as: CAB-381-0.1, CAB-381-0.5, CAB-381-2, CAB-381-20, CAB-551-0.01, CAB-551-0.2,  CAB-531-1 and other CAB series. These products are equivalent to Eastman's CAB resins. Thanks to its great performance, Cellulose Acetate Butyrate CAB is used in many industries, including: Coatings & Paints – improves durability and weather resistance Inks – enhances flow and adhesion Cosmetics – acts as a film-forming agent or additive It's a useful material for applications where strength, flexibility, and moisture resistance matter.
