I'm building a mechanism that should be compatible with a 1E-7 Torr environment.
(The chamber is sealed, and is pumped by a Getter)
There are a number of parts (e.g. a 4mm diameter by 15mm long push-rod, an M4 nut and washer) that need to be insulating.
I'm looking for a few good materials.
The chamber has to remain sealed for a long time relying only on the getter, so I need to go overboard with eliminating outgassing.
Thanks,
Ben.
