Rubber and its Types | Chemistry Learning
Synthetic Rubber. For example, Polychloroprene is inferior to natural rubber in some properties but superior in its resistance to oil, Organic Solvents. These differences are due to difference in nature of their monomers: Isoprene (for natural rubber) and Chloroprene (for synthetic rubber).

Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers.

Natural Rubber / Latex – Production of Natural Rubber
Processing of Natural Rubber. Processing of natural rubber involves the addition of a dilute acid such as formic acid. The coagulated rubber is then rolled to remove excess water. Figure 2. Rolling the latex into thin sheets. Then a final rolling is performed using a textured roller and the resultant rubber sheet is dried.
