Rubber vs. Silicone: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 15, 2024
Rubber is an elastic material from plants or petroleum, used for flexibility and strength; silicone is a synthetic polymer, heat-resistant and used in diverse applications.

Key Differences

Rubber is a natural or synthetic elastic material, derived from latex of rubber trees or made from petroleum products. Silicone, a synthetic compound, consists of silicon, oxygen, carbon, and hydrogen, known for its flexibility and heat resistance.
