There are two types of rubber, synthetic and natural, which are made using different processes. Natural rubber is made from the sap of the rubber tree, which is extracted from the tree and then mixed with sulfur and white lead and heated in a process known as vulcanizat...
The most common properties of rubber are its elasticity, resistance to water and its use as an electrical insulator. When raw rubber is heated, it becomes sticky, and when it is in colder temperatures, it tends to break, just like the synthetic variety.
Rubber was invented in 1839 by Charles Goodyear. He accidentally dropped Sulphur and white latex from a rubber tree on a hot stove. This resulted in the formation of a dark elastic substance which came to be called vulcanized rubber.
Rubber trees were first discovered by the Olmec, Maya and Aztec people. They used the sap to make rubber balls to waterproof their clothing and to make their own shoes and shoe soles. In 2014, the sap is used to process rubber for a variety of uses.
