Latex, also known as rubber, is a natural polymer obtained from the milky sap of the rubber tree (Hevea Brasiliensis), a plant native to the tropical forests of Central and South America. Depending on the use, following the tapping stage the latex milk is processed in different ways. They are not edible, so only weathering can break them down into their elementary particles. Tappers tend to these cups, collecting the latex when they become full and replacing the collection cups to continue harvesting from the tree until it is appropriately tapped. The tree also thrives in Southeast Asian plantations. These chemicals are used to create synthetic rubber polymers, which are clumped and dried, then transported to a manufacturing plant. Natural rubber comes from latex, which is produced by a tree called Hevea Brasilienesis. You get to see how the tree sap is harvested, collected and poured into a mould, and then cured at a high temperature.
