Bakelite? That's a likely for the car distributor, and is a high temp

Phenolic might work well, but it's not black.,,
Micarta might also work

Phenolic plastics were the first, and still the commonest,
thermosetting plastics (they take heat well).

The earliest, inventor Baekeland used with lots of
asbestos as reinforcement and filler. That is not a currently
available product.

Bakelite (Union Carbide), and Formica (General Electric) and
Micarta (Westinghouse) are all tradenames for phenolic plastics,
and nowadays use either wood-fiber (paper) or for high
performance, linen reinforcement/filler.
