Wow i'm surprised this is even a question. When we are talking about the type of filtration PVDF is the only way to go. No question. Especially for the temperature i filter at. Sometimes i'm filtering at just under 200 F. You can't use nylon for hot filtering.
Nylon is not compatible with Benzyl alcohol - even at 1% BA. Do not use it.
And I agree with Brundel, PVDF is superior choice for filtering, its chemical compatibility is excellent.
PTFE (teflon) filters are the absolute best, but they run a premium. PVDF is a fine choice.
Just some other FYI info for the board:
PES is not compatible with BB
Nylon is not compatible with BA
PES and Nylon are not compatible with Guaiacol, (and most likely not EO).
