Types of Rubber
1. Natural Rubber:
Natural rubber is obtained from the sap of a rubber tree (Hevea brasiliensis). When the rubber tree is tapped, the milky-white liquid obtained is called the rubber latex. Natural rubber can be improved upon by adding other chemicals at high temperatures. This process is called vulcanization.
2. Synthetic Rubber:
This class of rubber is known as ‘elastomers’. They are produced from petroleum products. Synthetic rubber cannot be vulcanized.
Rubbers are generally more elastic than plastic. This means that when rubber is stretched, it returns to its original length and size with ease.
Rubber is used to produce:
- Shoes, etc.
