The following table provides general guidelines on material compatibility with ozone.  Actual performance
depends on the environment (dry or moist air, water, concentration of ozone, whether the materials have
been modified for ozone service, etc) and application (polycarbonate is stable in the presence of ozone but
yellows over time which reduces its utility where clarity is important).  Consult your material vendor for
specific information.
