This material is derived from the rubber tree. Although numerous types of rubber trees can be found in nature, only one kind of rubber tree is used for industrial purposes. This industrial type of tree is cultivated in the Amazon Region, and referred as Heveabrasiliensis.In terms of natural structure, this material is not homogeneous. Nevertheless, this material was categorized in a different product group in accordance with the analytical criteria and evaluation of appearance.
Over 15 million tons of rubber is annually produced around the world. Approximately one third (1/3) of this production represents the natural rubber production. As for the remaining percentage, it represents the artificial (synthetic) rubber that is produced with chemical materials deriving from petroleum.
