Vulcanization is the process of treating rubber or other materials with sulfur or other substances to make them hard, tough and more resistant to wear and tear. There are several synonyms for the word vulcanization including hardening, toughening, solidifying, fortifying, and strengthening. These terms all have one thing in common: they describe the process of making something stronger and more durable. Vulcanization is particularly applicable to the rubber industry, and can also be used in other applications such as strengthening metals, plastics, and ceramics. Whether you're manufacturing tires or creating specialized parts that need to withstand intense heat and pressure, vulcanization is an important part of the process.
