The technique, which involves combining rubber with other materials, turns natural rubber into a durable, elastic material with many practical applications. Another term for vulcanization is “cure”.Vulcanized rubber won't deform as easily as regular, non-vulcanized rubber, but it may still distort if subjected to significant stress. When rubber is vulcanized, it also becomes harder, increasing its tensile strength and .

An international standard, ISO 2921:2019 – Rubber, Vulcanized – Determination Of Low-Temperature Characteristics – Temperature-Retraction Procedure (TR Test), helps test vulcanized rubber. Vulcan is the Roman god of fire, metalworking, and the forge. He’s even where we get the word “volcano”— the Italian volcano derives from the Latin Vulcanus.
