Before elaborating upon silicone rubber, one should first understand the differences as well as the similarities both silicone rubber and natural rubber possess. Silicone rubber is made from a mixture of silicon, oxygen, carbon and hydrogen making the final product very flexible as well as heat resistant and non toxic. As Thompson E. noted “Rubber is a plant extract and ideally possesses good elasticity but it is highly prone to environmental degradation.” This proves natural rubber to be an inferior option than silicone rubber.
