As we all know, the older one gets the less sharp the memory gets.
I am looking for a gasket material that resists high temperatures. Back when I worked at TRW Space Systems, we used it all the time between assemblies - it was good for -200F to +600F. Only problem is I don't remember what it was called. While I don't need that wide a range, I do need it to tolerate ~500F (lower range is room temperature and therefore not a consideration). I did a Google search of "high temp gasket" -- 50,000,000 hits and couldn't find what I was looking for. Tried "high temp insulation" - that was even worse.
So does anyone have a favorite gasket material good to +500F?
Machining - only cutting to shape, think donut. Thickness .063 up to whatever.
