Frequently Asked Questions
How many chemicals does this compatibility chart cover?
551 real media rows across 11 chemical families, rating each against PVC, PP, PVDF, PFA, PTFE, and 316 stainless steel at real tested concentrations and temperatures.
What does a blank cell mean on the chart?
No rating was published by the source for that specific chemical/concentration/temperature combination. Treat a blank cell as unknown, never as "safe" — confirm with LibertyCES before specifying.
Why does the same chemical show different ratings at different rows?
Chemical compatibility is concentration- and temperature-dependent, not a single yes/no per chemical. The same chemical can rate Good at a lower concentration/temperature and Fair or Corroded at a higher one — always check the specific concentration and temperature you're actually running.
Is 316 stainless steel always the safest wetted-parts choice?
No — this is one of the most counterintuitive findings in the chart. Against several chemicals (including all six Freon refrigerants), 316SS rates worse than PVDF, PFA, or PTFE. Don't default to stainless without checking the specific chemical.
