Natural rubber is mainly obtained from the sap of the Hevea Brasiliensis (rubber tree), a tropical tree species. This tree grows exclusively in a zone 15° north and south of the equator (rubber belt). Originally native to Brazil, the most important plantations are now located in Southeast Asia.
The liquid, also known as latex or milky sap, is usually released by scratching the bark of the tree.
Latex is an aqueous dispersion of rubber polymer particles that also contains resins, proteins and minerals.
The coagulated latex itself is used to make so-called diving articles such as gloves, balloons or condoms.
