Rubber is a natural polymer of isoprene (polyisoprene), and an elastomer (a stretchy polymer). Polymers are simply chains of molecules that can be linked together. Rubber is one of the few naturally occurring polymers and prized for its high stretch ratio, resilience, and water-proof properties.
The natural rubber market is coordinated by the Association of Natural Rubber Producing Countries (ANRPC). This intergovernmental association represents 92% of the world's natural rubber production. [20] There are a number of factors driving the search for alternatives to natural rubber production.
About 95% of isoprene production is used to produce cis-1,4-polyisoprene—a synthetic version of natural rubber. [14] Natural rubber consists mainly of poly-cis-isoprene with a molecular mass of 100,000 to 1,000,000 g/mol. Typically natural rubber contains a few percent of other materials, such as proteins, fatty acids, resins, and inorganic ...
Hevea brasiliensis is a tall deciduous tree growing to a height of up to 43 m (141 ft) in the wild. Cultivated trees are usually much smaller because drawing off the latex restricts their growth. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged.

The case is known as Flomo vs. Firestone Natural Rubber Company. [32] The lawsuit stated: The Plantation workers allege, among other things, that they remain trapped by poverty and coercion on a frozen–in–time Plantation operated by Firestone in a manner identical to how the Plantation was operated when it was first opened by Firestone in 1926.
