That's Phenolic.  Hasn't been used in decades AFAIK.

BTW when you see a white insulator in connectors, it is often High 
Density Polyethylene and not Teflon. It has very poor thermal 
characteristics and has a hot oil like smell when heated.  Put the tip 
of a small, hot, soldering iron in on Teflon and nothing happens, but on 
HDPE it quickly leaves a dent.  OTOH don't use a really hot iron on 
Teflon. When it breaks down, it releases a poisonous gas.

Held side by side the Teflon is a Whiter white while the HDPE  is 
slightly darker and very smooth...almost slippery to the touch.
