A common question when implementing ozone into a new application is how will ozone affect the materials we currently have in place. Below is a useful chart showing the resistance of common materials to ozone oxidation.
A = Excellent – no effect from ozone in normal operation
B = Good – some oxidation from ozone, these materials can work with low ozone concentrations or short-term (less than 6-month) usage
C = Fair – major effect from ozone oxidation, these materials should only be used for short-term applications or very low ozone levels
D = Poor – severe oxidation from ozone will be noticed quickly.
