Ebonite applications from the 19th century. Ebonite is a brand name for a material generically known as hard rubber or vulcanite, obtained via vulcanizing natural rubber for prolonged periods.

Excessive crosslinking can convert the rubber into a hard and brittle substance (i.e. ebonite).

Longer crosslinks, with higher numbers of sulfur atoms, give the rubber improved physical durability and tensile strength.
