CARBON DIOXIDE (EXPLOSIVE DECOMPRESSION USE) Chemical compatibility with O-rings, rubbers, & plastics

Carbon dioxide, also known as CO2 or carbonic anhydride, is a colorless, odorless gas widely used in carbonated beverages, refrigeration systems, welding applications, and fire suppression equipment. While CO2 is generally non-toxic, high concentrations can displace oxygen and create asphyxiation hazards. In sealing applications, compatibility with O-rings, rubber components, gaskets, and plastic materials must be considered, especially under pressure where rapid decompression may affect elastomers. Proper storage, ventilation, and system design help ensure safe operation and reliable rubber sealing performance.
