The two types of rubber are natural and synthetic rubber. Natural rubber is made from the latex obtained from rubber trees, while synthetic rubber is obtained from petroleum products. In each case, the resulting high-quality rubber is too hard to be processed easily.

So, the first step in processing rubber is to break it down to make it smoother and more malleable. In order to get an even mixture, we blend the rubber with certain chemicals and softeners. 

Carbon black (fine carbon obtained from wood, bones, or plants) is added in order to make the rubber product stronger. After thorough mixing, the rubber is then ready to be formed.

Rubber products are formed by processes similar to those used in making plastics.
