Rubber

Rubber is a type of material called a polymer. It can be produced from natural sources (e.g. natural rubber) or can be synthesised on an industrial scale. Many things are made from rubber, like gloves, tires, plugs, and masks. Some things can be made only from rubber. Sometimes the word means only natural rubber (latex rubber). Natural rubber is made from a little wood from an oak tree such as the Hevea brasiliensis (Euphorbiaceae). Synthetic rubbers are made by chemical processes.
