Leaf switch spacers

Does anyone know what the insulation material is that are used in leaf switches?

They come is varying thicknesses and the one on the left, is the top and bottom friction cap. This holds the whole assembly together.

Got a message that it's Bakelite Phenolic Resin. Though that Pertinax/Phenolic looks right as well.

Apparently they were supplied in bar format. The holes were then drilled in and the bar sliced to the correct thickness.

Quick Google search found this, very similar looking:
