- PVDF is used extensively in the chemical industry because of its chemical
- resistance to most materials. In fact, it is used as a replacement for PTFE
- (Teflon) in many applications because of superior mechanical properties with
- only a slight decrease in chemical resistance. Finding a solvent for
- polyvinylidene difluoride will be very difficult.
-
- Having said this, however, I will add that one of our commercial high boiling
- point solvents, Ektasolve EEP, has been known to attack PVDF. In our
- manufacturing process for EEP, Kynar (PVDF) coated pH probes were dissolved
- away completely as were Kynar insulated electrical conductivity probes. I
- am not sure this solvent will meet your needs however.

- Why do most net posters always mistakenly spell fluorine containing compounds
- as if they were bakery products? ;-)
