What is Vulcanised Rubber?
Vulcanized rubber is a processed form of natural rubber that has been chemically treated to improve its properties. This process, known as natural rubber vulcanization, involves heating raw rubber with sulfur or other curing agents. The result is a material that is stronger, more elastic, and resistant to extreme temperatures, wear, and chemical exposure.
Before vulcanization, natural rubber was soft, sticky, and unstable in varying weather. The introduction of this process revolutionized rubber’s usability, making it suitable for industries like automotive, construction, medical, and consumer goods.
The Invention of Vulcanized Rubber
The discovery of vulcanized rubber is credited to Charles Goodyear, who, in the mid-19th century, accidentally found that heating natural rubber with sulfur transformed it into a stronger, more durable material. This chemical reaction, later known as the vulcanization process, marked a turning point in the rubber industry.
Before Goodyear’s breakthrough, natural rubber was unreliable—becoming sticky in heat and brittle in cold. By introducing the process of vulcanization of rubber, Goodyear created a material that could hold extreme conditions, paving the way for its widespread use.

What is the Vulcanization of Rubber?
Vulcanization is a chemical process that transforms natural rubber into a more durable, elastic, and heat-resistant material. This process addresses the limitations of raw rubber, such as stickiness in heat and brittleness in cold, making it suitable for diverse industrial applications.
The Rubber Vulcanization Process
The vulcanization process of rubber involves-
- Heating natural rubber with sulfur (or other curing agents).
- This causes a chemical reaction that forms cross-links between rubber molecules, creating a strong and flexible structure.
- The result is a material that retains its shape and strength under stress, heat, and environmental exposure.
What Does Vulcanisation Mean for Rubber?
Vulcanization means that rubber becomes-
- Resistant to wear and tear.
- Flexible while maintaining strength
- Stable across extreme temperatures
