No, not if my memory serves me right.
Paxolin is the sort of stuff that tag boards and early printed circuit
boards were made of. I.e. it's brown and sort of laminated.

I think "Paxolin" might be a brand name, but the material is an
impregnated laminated fibre or paper, used exactly as you say.
The stuff has a very distinctive smell when heated (eg, when being cut
with a saw).Â* There's a place a few miles from here that makes (or
used to make) circuit boards to order. You often get that smell as you
pass.

Bakolite is an early plastic that was used to make moulded items like
plugs etc. It's often dark brown but doesn't have to be, it's quite
hard and doesn't melt, it chars if you make it very hot and smells.

I wouldn't be sure that bakelite is in current use. The world doesn't
really have much use for non-thermoplastic, brittle materials any more.

Of course it does.
What the **** is china if not brittle, and not thermoplastic?

Perhaps I should have added the qualifier: ...and which does not need to
be glazed, washable and still hygienic after being scrubbed hard by a
hard brush with hot water and soap.

What the **** do you think Formica is? It started out as bakelite

Formica is closer to Paxolin, I'd say.

Phenolic resins are still in use

Did anyone say they weren't?
