Choosing a seal material for Cellulose Acetate Butyrate

The table above rates every common O-ring elastomer for service in Cellulose Acetate Butyrate on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.

For Cellulose Acetate Butyrate, the strongest candidates are Perfluoroelastomer, Ethylene Propylene, Silicone, Fluorosilicone, Neoprene (Chloroprene), Natural Rubber, Styrene Butadiene, Butyl. These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
