8. What is the difference in information about rubber, silicone?

how to caulk without a gun

Rubber and silicone

They are polymeric materials with viscoelastic activity, commonly referred to as elastomeric. Silicone is distinguishable from rubber by its structure.Besides, silicone has more properties than ordinary rubber. Natural rubber occurs, or they can be synthetic. Based on this, silicone can be distinguished from rubber.

  • Silicone is one of the elastomers or one of the rubbers.
  • The backbone of silicone contains silicon and oxygen, while the backbone of most other rubbers contains carbon-carbon bonds.
  • Silicone is more resistant to heat, chemical attack, fungal attack, UV and Ozone than normal rubber.
  • Silicone is better than all other rubbers because of thermal insulation due to heat resistance.
  • Silicone rubber offers special properties, which organic rubber does not have. Organic rubber has poor corrosion resistance at high temperatures while these properties are excellent in silicone rubber at the same temperature conditions.


In general, all elastomers are considered rubber, in that the size can be changed mainly by pressing, and can be returned to the original size after removing the tension. 

But natural rubber is what we think of when we consider rubber. Natural rubber is obtained from the rubber of Hevea Brasiliensis. Most rubbers contain polymer chains of carbon. However, silicone rubber contains silicon in the polymer chains instead of carbon.

Silicone is a synthetic rubber. It is synthesized. Silicone consists of a backbone of silicon atoms with alternating oxygen atoms. Unlike other elastomers, silicone’s inorganic backbone makes it more resistant to fungi and chemicals. 

Rubbers are used for many applications such as cookware, electronics, automotive applications, etc., because of their elastic behavior. Since they are waterproof materials, they are used as sealants, gloves. Rubber or elastomers are excellent materials for insulating purposes.

Of all rubbers, silicone is much better for insulation due to its heat resistance. Silicone rubber offers special properties, which organic rubber does not possess.
