rubber vs silicone

Elastic and user-friendly items provide convenience throughout our everyday life. In fact, the popular usage of these polymeric fabricated materials is becoming one of the latest trends today, especially in the fields of medical surgery, production of construction supplies, cosmetics, dermatology and many more.

Two of the most commonly used polymer materials that exhibits elasticity, flexibility and durability are rubber and silicone. These polymeric materials are good electric, heat and thermal insulators. The main differences of these two materials are the substances that constitute their atomic structures.

Rubbers cover many types such as natural, styrene butadiene, synthetic, poly isoprene, nitrite polychloprene and silicone. A natural rubber is extracted from the latex of a plant named as Heveabrasiliensis. In the world of physics, it is described as the atomic structure having CIS -1 -4 –poly isoprene. Most rubbers constitute carbon in their chemical compound structure. Rubbers characterized electric resistance and served as a good insulator against electrocution.

Silicone is a type of rubber primarily made of synthetic substances. Its atomic structure derived from the combination of silicon and oxygen atoms which is formulated as R2SiO. One of its major advantages compared to an ordinary rubber, it is resistant to fungus, heat, ozone, UV attacks and other chemicals. Its resistance to heat is made possible due to the presence of oxygen in its compounded structure. It has excellent tensile and tear properties against extreme temperatures. However, silicone has high viscosity characteristics that makes it weaker compared to an organic rubber.
