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.

Indeed. Officially I think it is SRBP

Synthetic Resin Bonded Paper industrial laminate

Available in two grades, only one being suitable for high voltage
applications.

When GEC took over AEI, guess who built a set of AC locomotive 25
kV tapchangers with the wrong grade, because of different factory
norms. There was a bit of a bang! :-(

For greater physical strength there is also SRBF, which has
fabric reinforcement.
