Caoutchouc

Rubber tree Hevea brasiliensis

Description

A French term used in Brazil for the elastic sap obtained from various tropical plants from the species Hevea and Ficus. Caoutchouc normally refers to the plant resin, or raw rubber before processing. In 1836, the name caoutchouc was also used for a commercial rubber-based cement in which a small amount of the elastomer was dissolved in a solvent and mixed with mastic. Today, the material is preferentially called Latex or liquid rubber.
