Natural Rubber vs. Vulcanized Rubber: What's the Difference?

Reviewed by Huma Saeed || By Sara Rehman || Published on December 9, 2023
Natural Rubber refers to elastic material obtained from latex of rubber trees. Vulcanized Rubber refers to natural rubber chemically treated with sulfur to enhance durability and heat resistance.

Key Differences

Natural rubber is a soft, elastic substance derived from the latex of rubber trees, primarily used in its raw form. Vulcanized rubber, on the other hand, is natural rubber that has undergone a chemical process involving sulfur to improve its properties.
