Hi Phil:
- During a 30+ year career as a civil servant (or was that simple serpent) for
the U. S. Navy one of my assignments was as Program Manager for the USN
(COMNAVAIRSYSCOM) avionics repair (2M) program.  In so doing I came in contact
with Kapton insulated wire, and Yes, during the Southeast Asian peace games
(held in/above Vietnam) we had some problems with Kapton insulation and, if
memory serves me correctly, it was indeed banned for new designs.  As I recall
we tried to purge it from Naval Air Rework Facilities (NARF's) but were not
completely successful due to the huge amounts on-hand and the high cost of
procuring replacement materials (something about budget limitations and
limited risk).  I seem to recall some rumors that Kapton would ignite (after
being conditioned by exposure to certain chemicals present in fuel systems)
when exposed to impact such as small arms fire or other mechanical
shock/vibration.  I never had access to any of the test report data and
therefore cannot confirm/deny the validity of the rumors.
- Hope this helps muddy the already turbid water.  Regards, Jim Moffitt
