"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:
