What is Vulcanized Rubber?

Vulcanization is a process used to create cross-links between the molecular chains of rubber, which improves its mechanical properties and resistance to heat and chemicals. The resulting material is called vulcanized rubber.

Vulcanization is achieved by treating rubber with sulfur compounds, which form cross-links between the molecular chains. This process was invented in the mid-19th century by Charles Goodyear, who discovered that adding sulfur to rubber improved its strength and durability.

The term "vulcanize" comes from the Roman god of fire and volcanoes, Vulcan, because the process involves heating the rubber to a high temperature (like a volcano) to create the cross-links.

So, vulcanizate is the resulting material that has undergone the vulcanization process. It is a thermosetting plastic that is strong, flexible, and resistant to heat and chemicals, making it useful for a wide range of applications, such as tires, hoses, belts, and gaskets.
