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.

If a connector has Amphenol on it, can I assume it is a good one? I see
several Amphenol connectors on eBay for a pretty good price now and
then.
