In Reply to: It is not advisable to melt Teflon. posted by snert on March 24, 2007 at 08:38:09:
In my youth I worked in the missile business and we stripped miles of teflon wire using thermal strippers which produced a puff of smoke with each strip. And I'm so healthy and normal that I'm an audiophile!It's the people that thought we should build them that were sick and crazy, and I don't think they stripped a single wire...

teflon has flourine in it's chemical composition. It used to be banned in certain US Submarine applications because of the potential of the reactive flourine
Hi Stu,You mentioned that "teflon has flourine in it's chemical composition".
It certainly does, that's what makes it good! Fluorine is so reactive that it really clings to it's electrons so there's darned near no conductance or RF loss. And that's good for audio too...
On the other hand if it does come apart that same reactivity probably makes it bad for the bod since it bonds so readily.
However using a thermal stripper apparently doesn't release enough to be terribly unhealthy as a lot of us are still kicking. So I suspect that doing a match test on a wire end isn't much of a risk.
Now a fire in a submarine... Talk about inadequate ventilation!
That's nicely stated.

I have worked with flourocarbons for over 30 years. I know what phosgene smells like and what it can do.
Well... my posting was rather tongue-in-cheek, albeit true. I really have no idea how risky using thermal strippers on Teflon is but I'm sure they should be used with adequate ventilation. The place wasn't exactly health conscience. We had highly recirculated air, used about a dozen tanks of CO2 a day, did a lot of soldering, scrubbed everything with toluene and potted stuff with a foam that out-gassed cyanide all in one big room. Ah the "good old days" before OSHA...
