See my earlier comment on the specific gravity of Turcite
B. The higher density would be consistent with a metal
filled PTFE.

Say, have a look at:

http://www.busakshamban.us/pdf/mds_t47.pdf

Turcite T47 == Bronze-filled PTFE w/ sp gr 3.02 to 3.14.

Makes you wonder why they're right out front with this and
there's so little info on the composition of Turcite B.


Lots more he

Seems the trademark "Turcite" applies to anything, pure PTFE, UHMW-PE,
bronze-filled, graphite-filled, carbon fiber, etc.


That's not too unusual. One of the best references on the
common engineering plastics I have is put out by Erta. They
list properties of acetal, various nylons, PET, etc., but
they're all called Erta(something).
