stcreef said:Cast acrylic will not be affected by Ozone. But the plastic in the pump may be affected in the long term. Any butyl rubber will be as well. Most polymers will be affected but only if they are NOT cast. Casting creates a different chain in the polymer double chain. So if its extruded or injection molded, it will be affected. If its cast, it wont.
PVC is an exception. Well not really in our application. But an extreme amount of ozone will cause chlorine to actually precip out of chain. But you cant create that much ozone at home.
This all applies to ozone in gas form, in solution most will be safe.
