What is Rubber?

Rubber is a polymer which can stretch and shrink. It occurs naturally and can be synthesized as well. We have been using rubber products since ancient times. But during the 19th century it became a highly useful industrial raw product for various purposes.

Types of Rubber

Rubber can be divided into following two types based on its origin –

  • Natural Rubber

  • Synthetic Rubber

There is a wide variety of synthetic rubber available such as EPDM (Ethylene Propylene Diene Monomer) rubber, commercial black rubber, SBR (Styrene butadiene rubber), NBR (nitrile butadiene rubber), IIR (Isobutylene-isoprene) etc.

What is Natural Rubber?

Natural rubber is a natural polymer of organic compound isoprene obtained from the bark of tropical and subtropical trees. The milky white fluid which is obtained from trees is called latex. This is the reason natural rubber is also known as latex. Natural rubber is also called India rubber, Amazonian rubber and caucho. Leading producers of natural rubber are Thailand and Indonesia.

Monomer Unit of Natural Rubber – 2-methyl 1,3-butadiene (it is also called isoprene)

Structure of Natural Rubber – It is called polyisoprene or cis-1,4-polyisoprene. Its structure is given below –

Preparation of Natural Rubber

Natural rubber or rubber latex is directly collected from plants. Then it is processed for common use by various methods. It is a polymer of 2-methyl 1,3-butadiene (or isoprene).
