Just a friendly warning to be careful of what you read.
A very well respected manufacturer of connectors, claims that a particular connector has Teflon insulation. There aren't a whole lot of this sort of connectors with this sort of insulation. However, if you take a 350F soldering iron to this insulation, it will melt easily. If you compare it to the standard white POM (Delrin) insulation in other plugs, you will see that it has the same melt and burn behavior and the same smell. There is no Teflon formulation that melts at 350F, if you go through all of Dupont's literature.
So, if you have a connector of any sort that claims to be insulated with Teflon, set your iron to 350 and give it a poke. It shouldn't do anything when you do this, nor should it do anything at 450. This isn't the only connector out there with embellished materials claims. Do your homework and you won't get ripped off.
