Why is rubber used to make tyres?

           Rubber is the most preferred material to make tyres. It is an elastic polymer formed by the addition of isoprene monomers. When stretched, the monomer chains arrange themselves in a linear fashion.

           Rubber does not transfer heat. It is flexible and easy to mould into any shape. It has a greater friction as well. These qualities are desirable for tyres. In addition to this, it can be strengthened using additives that would make it strong, flexible and durable.

           Rubber melts at temperatures above 180 degrees celsius. Some of you might have visited rubber plantations. Have you ever smelled rubber while it is being made into sheets? It produces a severe bad odour while it is being processed. This is because of the production of hydrogen sulphide gas due to several chemical reactions.
