We provide a detailed explanation of the Rubber Vulcanization Process, including the role of the vulcanizing agent, temperature control, and reaction mechanisms. Discovered by American chemist Charles Goodyear in 1839, vulcanization is a chemical process that transformed the rubber industry. 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 .

5.1 This test method is used to determine the vulcanization characteristics of (vulcanizable) rubber compounds. 5.2 This test method may be used for quality control in rubber manufacturing processes, for research and development testing of raw-rubber compounded in an evaluation formula-tion, and for evaluating various raw materials used in . 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.
