Effect of lubricants on PTFE/PTFE friction under high pressure.
Effect of lubricants on PTFE/PTFE friction under high pressure.
(OP)
I have two surfaces coated with thin PTFE sheet which will be under high pressure (possibly up to 150 ksi/1000 MPa). I wish to minimise friction between them for very small amounts of movement (maybe 0.05"/1 mm) at very low speed (a minute or two for that movement). Getting any sort liquid between the surfaces would be very hard, but what about a dry lubricant? Could there be any benefit?
Any thoughts much appreciated.

If there's genuinely no point in adding anything then in some ways it would be a good thing: due to the nature of the specimen we have to add any lube before curing it (350 deg F), so we can't test with and without easily.
