How is rubber made today?
Natural rubber is made by extracting a liquid sap, called latex, from certain types of tree. These trees are native to South America but are today commonly found in Southeast Asia. Latex is gathered from the trees by making a cut in the bark and collecting the runny sap in cups. This process is called tapping.

Why is natural rubber better than synthetic?
An advantage natural rubber has over synthetic rubber is that natural rubber has higher tensile strength, higher tear resistance, and low odor compared to IR. In addition, synthetic rubbers can have excellent heat resistance, lower temperature resistance, and heat aging improvements.
What is natural rubber used for?
Natural rubber, or latex is used mostly in car tyres and medical products. Vulcanised rubber is mainly used to produce automotive tyres, however there are a large number of additional applications, including seals and medical products (e.g. surgical gloves).
