What makes vulcanised rubber different to an ordinary rubber?

Vulcanised rubber is created through a chemical process that involves heating natural rubber with sulfur, which forms cross-links between polymer chains. This process enhances the rubber's durability, heat resistance, and elasticity, making it more suitable for a variety of applications. In contrast, ordinary rubber lacks these cross-links, resulting in a material that is more prone to degradation, deformation, and lower performance under stress. Overall, vulcanised rubber offers improved mechanical properties and longevity compared to non-vulcanised rubber.
