"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.
The only information I *do* know is that pure PTFE cold-flows - a
lot. It would be a poor choice for way sliders.
I just discovered this MSDS from the mfr which states the Turcite B is
indeed just PTFE:

I don't see it saying Turcite B is just PTFE. True, in section 2
it lists nothing besides PTFE (polytetrafluoroethylene) and
Chromium III Compound (0.5% by wt.) as hazardous ingredients.
But in section 8 it says "This compound contains Chromium III
compounds [...] and 25% Cu metal".
