Sulfur vulcanization, the more traditional method, uses sulfur to create cross-links between rubber polymer chains, enhancing flexibility and durability. Sulfur vulcanization is a chemical process crucial to the rubber industry, transforming raw rubber into a durable, elastic material. This process

On the other hand, peroxide vulcanization uses organic peroxides to form cross-links, resulting in rubber that withstands higher temperatures and chemical exposure better than sulfur-vulcanized rubber. Each method offers distinct properties to the rubber, tailored to specific applications and

Various types of accelerants exist, including liquids, solids, and gases, each with specific properties and applications. 370:) are used, fires produce more heat, consume fuel more quickly, and spread quicker. Fires involving liquid accelerants like gasoline burn quicker, but at the same temperature as fires involving ordinary fuels. 408:

Vulcanization of rubber can be categorized primarily into two types: sulfur and peroxide vulcanization. Both chemical processes are examples of using an accelerant.
