That was the main point brought up earlier in the thread w/re: Teflon coated wire.past wire discussions, I recall people talking about which coatings were less likely to melt when soldering.
As far as its melting point, i can't say for sure on wire, since I haven't tried any yet, but 3D printer bowden tubes are Teflon, and the ones that come with a printer really cant handle setting extruder temps above ~230° C, higher quality ones maybe up to 250°C. But that's constant heat where it seats up against the top of the hot end.
Based on that, I'd wager small durations of 350–380°C (or whatever you solder at) might be okay, since Teflon, as I understand it doesn't curl up as immediately or profusely as PVC. But please correct that interpretation if it's off. It's the fumes from sumbliming(??) Teflon that are toxic as the real danger of temps.
