[8] : How Is Natural & Synthetic Rubber Produced?

Today more than 90% of the natural rubber supply comes from South-East Asia. As rubber trees require a hot, damp climate they grow only in the “Rubber Belt,” an equatorial zone that stretches around the world. General purpose synthetic rubber has its origin in two gases: Butadiene which is a by-product of petroleum refining, and Styrene which is captured either in the coking process or as a petroleum refining by-product.
