I believe the Tornado was (is?) still full of the stuff, due mainly to it weighing less and being less bulky than just about any other type of insulation then available. I remember attending an early Q course were the carbon arc tracking video was shown. I am sure several losses were attributed to this. The footage looked to be quite old even then.
Has kapton got anything to do with Nimrod? I don't know, but I'm fairly certain that civil fleets spent a lot of effort in getting the stuff removed.
