RE: PVDF Chemical Compatibility

Not listed. Nitrobenzene (very similar chemical) is listed at room temperature only and is rated 7-8. Based on the ratings I'm seeing for other related plastics at elevated temperature with nitrobenzene I'd be hesitant to use it with PVDF. Ask the manufacturers.

RE: PVDF Chemical Compatibility

(OP)
Several articles cite that liquid dinitro toluene attacks some form of plastics, rubbers, and coatings with no further details. Is it possible a common molecular structure/Bond that DNT reacts with, such as C-H bond?

After looking into several chemical compatibility charts, it appears that only few materials can handle DNT, including PTFE and FFKM and some other metallic material.
