There are two types of rubber: natural and man-made (synthetic).
Natural rubber is made from the combination of latex and other organic resources.
Synthetic or man-made rubber is constructed entirely from artificial materials. The creation of synthetic rubber was made in response to a lack of plant sap, or latex, resources in certain countries in the early 20th century. Synthetic rubber has proved to be a very successful substitute. In fact, synthetic rubber is generally more durable and stronger than natural rubber.
