ebonite
Ebonite is a hard, non-flexible substance made by vulcanizing natural rubber for prolonged periods. It is often used in various applications due to its excellent electrical and thermal insulation properties. It's most commonly black and has a high sulfur content, which gives it a characteristic strong smell. Its name is derived from its similarity in appearance to ebony wood.

Ebonite
Ebonite was a brand name for very hard rubber first obtained by Charles Goodyear by vulcanizing rubber for prolonged periods. It is about 30% to 40% sulfur. Its name comes from its intended use as an artificial substitute for ebony wood. The material is known generically as hard rubber and has formerly been called "vulcanite", although that name now refers to the mineral vulcanite.
The Standard Electrical Dictionary

It is used in electrical apparatus for supporting members such as pillars, and is an excellent material for frictional generation of potential. Its black color gives it its name, and is sometimes made a point of distinction from Vulcanite, q. v.
