Fiberglass exposed to Ozone
Fiberglass exposed to Ozone
(OP)
I have been looking for information regarding the suitability of using fiberglass gratings/railings in a water treatment plant with ozone concentration less than 1 ppm in the air. It seems that understanding the ozone concentration in the information I have been able to find is elusive, and Stongwell and Fibergrate have contradictory recommendations.
Page 18/19 of the Reichold publication (link below) suggests that FRP exposed to ozone may experience etching, but this appears it may be at higher concentrations in the water phase.

Ozone Solutions rates FRP as “Poor”, however the tests are reported to have been done “… at very high levels of ozone concentration.”
http://www.ozonesolutions.com/info/ozone-compatibl...
Fibergrate lists both their polyester and vinyl ester resins as suitable for continuous exposure to “ozone for sewage treatment”
http://www.fibergrate.com/media/3865/chemres.pdf
However, Strongwell list both polyester and vinyl ester grating and shapes as “Not Recommended” for ozone (page 18/19).

Any additional information or experiences using FRP in an ozone atmosphere would be appreciated.

RE: Fiberglass exposed to Ozone
After saying all that, I wouldn't expect that this concentration of ozone wiuld harm the FRP.
