Teflon? You maybe mean turcite, or rulon.

Plain PTFE would be a poor choice for a way bearing
surface IMO.

"Turcite" (not turcite) is just a brand name. My understanding is that
Turcite B is PTFE, and Turcite A or TA and TX or X are acetal-PTFE
copolymer. If you have some other information, I'd like to hear it.


Both Turcite and Rulon are families of filled or reinforced
PTFEs. I don't believe any of the flavors are straight
Teflon. Both my mill and lathe have this stuff on the ways,
though I don't know whether it's turcite or rulon or
another brand. It's definitely not plain Teflon--it's much
harder and more resistant to abrasion and gouging.

I've never seen any credible evidence that these materials
last longer than a properly maintained traditional way, but
they do make a noticeably improvement in the "feel" of the
machine by reducing stiction.
