Difference between Silicone and Rubber

Main Difference

After you check the meaning of these two words scientifically, you will come to identify that the main difference between the Silicone and the rubber is the atomic structure which is not similar in both of these materials. The special properties of the silicone are large in number as compared to the normal rubbers. Looks wise, they are very different from each other. The rubber is the material which is present on earth by nature, but they are able to be synthesized in addition. On the other side, the silicone is not present by nature because it is a human made thing. Due to this reality, when the rubber is synthesized, it changes to give us the silicone. Both of them are the elastomers containing different sorts of properties such as the Silicone is more opposing to the heat, chemical attacks and the fungus attacks in addition to the UV and Ozone assaults than that of the normal rubber. If you critically check the structure of the silicone, you will come to know that it contains the elements of silicon and oxygen. While the structure of most of the rubbers present on the face of this planet these days is available in the shape of carbon-carbon bonds. As the silicone is a form of rubber, that’s why it is basically a rubber. It is not obligatory that every rubber should be a silicone at the same time. Using the silicone is the much better option in the thermal insulation process because it has the ability to bear more temperature than the rubbers. The natural procedures of the strings of atoms which are known as the polymers are responsible for the creation of rubbers which are based on the element of carbon. From the name of the silicone, you can easily guess that the basic constituent element in silicone is the silicon. The durability and the strength of the silicone is much better than that of the rubbers.


siliconeSilicone is formed after the completion of the synthesis process made on the rubbers. In order to perform the procedure of the synthesis on the rubbers, the role of the modifying silicon is vital. In order to generate the silicone, the role of the backbone silicon atoms with the alternating oxygen atoms is necessary which will generate the high energy silicon-oxygen bonds. The silicone contains the feature of more resistant to heat as compared to the other rubbers or elastomers. In the same manner, this is the silicone which shows more resistance to the fungus and chemicals. The silicones have the higher resistant to ozone and UV attacks as well due to the company of the silicon oxygen bond. The silicon and oxygen bond present in the silicone is less susceptible to these attacks than the carbon- carbon bond present in other elastomers by and large. You will acquire a lower tensile strength and inferior tear strength as compared to the organic rubbers while using the Silicone. The use of the silicone is the best available option for you in the situation when the high temperature is present. Silicone is very durable as compared to other elastomers. The disadvantages which you will find in the silicone are composed of the shorter fatigue life, having the high viscosity than those of the organic rubbers causing the manufacturing problems due to the poor flow properties and some others.


rubberIt is a general conception that all the elastomers are rubbers. The dimensions of the rubbers are able to be changed largely with the help of stressing. If you wish to get the original dimensions once again, you only need to remove the stress. A glass transition temperature is shown by these materials because they have the amorphous structure. Lots of rubber types can be found at the present day consisting of the natural rubber, synthetic poly isoprene, styrene butadiene rubber, nitrile rubber, polychloprene, and silicone as they come in the category of rubber. In common terms, the word of rubber give you an idea about the natural rubber only. The process of obtaining the Natural rubber is very simple for which you only need to gain the latex of the Heveabrasiliensis. The structure of the natural rubber is Cis-1, 4-polyisoprene and it contains the polymer chains of carbon in most of the cases. The utilization of the Rubber is far above the ground these days such as in the preparation procedure of the cookware, electronics, automotive applications and lots of others because they have the feature of elasticity. The Rubbers are the elastomers which are best for the insulating purposes as well.

Key Differences

  • Rubbers can be found in lots of kinds including the silicone in addition and thus, every silicone is rubber but every sort of rubber is not the silicone.
  • The silicone is made because of the silicon and oxygen while the rubbers are made due to the carbon-carbon bonds.
  • Rubber is less resistant to heat, chemical attacks, fungus attacks, UV and Ozone attacks.
  • The thermal insulation can be completed more efficiently with the help of the silicone as it presents more heat resistance then that of the natural rubbers.
