think the story is that it was invented as wiring insulation for the
Mercury capsule, but with the recent press stuff about it, I've seen
reports that it was actually invented in the '30s. Which is it?


And it's a terrible thing to use for wiring insulation, since it
cold-flows. It's banned for use in most aerospace applications that I
am
aware of.

In most aerospace electrical applications, perhaps. It's widely used as
a seal material for low and moderate pressure fluid components in
aerospace applications.


Oh, of course. Aerospace *electrical* applications is what I intended
to
imply.

And to answer the other post, partly because it's compliant, but mostly
because it's chemically pretty inert. No problem at all sitting in NTO for
15 years.


And of course, heat tolerance.
