Rubber vulcanization is a process in which natural or synthetic rubber is heated in the presence of sulfur or other chemicals to increase its strength, flexibility and resistance to weathering and chemical attack.

The history of rubber vulcanization dates back to the early 19th century, when American inventor Charles Goodyear experimented with natural rubber, which at the time was only used for waterproof shoes and inner tire linings. Goodyear discovered that by heating rubber with sulfur, he obtained a material that was much more durable and resistant to the elements.

Vulcanization technology developed rapidly, and new types of synthetic rubber began to appear on the market. In the 1930s, synthetic rubber began to be used in the production of automobile tires, which contributed to the rapid development of the automotive industry.

Today, rubber vulcanization is used in a wide range of industries, from tire and rubber hose production to the pharmaceutical and cosmetic industries. The process continues to be crucial to the production of high-quality and durable rubber products that are used around the world.
