What does vulcanisation mean?
Vulcanisation is the process of transforming raw natural rubber into a tougher, more resilient material by treating it with heat, sulphur, and sometimes other additives. The change is chemical: sulphur creates cross-links between rubber molecules, helping the material withstand stretching, heat, abrasion, and ageing. The process is especially important in the manufacture of tyres, hoses, seals, belts, and numerous other rubber products. In British English, the usual spelling is vulcanisation; American English generally writes vulcanization. Although the word is closely associated with industrial manufacturing and engineering, it can also describe the treatment of rubber in laboratory, craft, and recycling contexts. The term is appropriately technical rather than everyday, but recognising it helps explain why ordinary rubber products can be both flexible and durable. Its name comes from Vulcan, the Roman deity associated with fire and metalworking.
nounVulcanisation is the chemical process of converting natural rubber into a stronger, more durable material by heating it with sulphur and other additives. The resulting material is known as vulcanised rubber.
- The process of treating rubber with heat and sulphur, or with related chemical additives, to improve its strength, elasticity, durability, and resistance to ageing.
"Vulcanisation gives natural rubber greater strength, elasticity, and resistance to heat and ageing."
"The vulcanisation of rubber is essential for manufacturing tyres and many other elastic products."
"Engineers studied vulcanisation to determine how the curing time affected the material's long-term performance."
The plural is rare; the uncountable form is normally preferred.
"The study compared different vulcanisations of the same rubber compound."
Vulcanisation is named after Vulcan, the Roman god of fire and metalworking—an especially apt name for a heat-based transformation of rubber.

Etymology of vulcanisation
The English term is based on Vulcan, the Roman god of fire and metalworking, whose name itself comes from Latin Vulcanus. It was coined for a heat-and-chemical treatment of rubber that transformed its properties. The related English words volcano and volcanic also derive from the name Vulcan, through the language of the Italian volcano.
