What does vulcanized mean?
Vulcanized describes material that has undergone vulcanization, a process that uses heat and pressure, usually with sulfur, to improve rubber by forming a durable network of cross-linked molecules. The result is harder, stronger, more elastic, and better able to resist heat, abrasion, and weathering than untreated raw rubber. The word is most often associated with tires, footwear soles, seals, hoses, and other rubber products. As a past-tense or past-participle verb, it identifies the action of treating rubber in this way. In everyday contexts, vulcanized is more informative than merely cured because it identifies a specific industrial process rather than an unspecified method of hardening. The term is especially familiar from the history of rubber manufacture, in which overcoming the shortcomings of raw rubber transformed transportation and many other industries. Its vocabulary and spelling also reflect British and American forms: vulcanized is common in US English, while vulcanised is widely used in British English.
Having undergone vulcanization, especially having been hardened and strengthened by heat and pressure, often with sulfur.
"The valve is made from vulcanized rubber that remains stable under pressure."
Usually used attributively with rubber, tires, soles, seals, and related manufactured products.
To subject rubber or another suitable material to vulcanization.
"The manufacturer vulcanized the rubber in a heated press."
This is the past tense and past participle of vulcanize and is chiefly used in technical and industrial contexts.
Vulcanized rubber gets its name from Vulcan, the Roman god of fire, because heat transforms raw rubber into a tougher, more useful material.
