Rubber tapping in Indonesia, 1951. Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches (150 mm) in diameter ...
Ridley spent many years promoting rubber as a commercial product, which he was known for being passionate; therefore, he was nicknamed "Mad Ridley". [9] In 1895, he discovered a means of tapping which did not seriously damage the rubber trees. [7]
Slaughter tapping is an obsolete method of extracting large quantities of natural latex from rubber trees in a forest environment. Before commercial exploitation of latex-bearing trees such as Hevea brasiliensis in the Amazon Basin and Funtumia elastica in the Congo, native populations limited harvesting to non-lethal tapping of the latex.
They replaced native trees, including those with medicinal or ritualistic value such as the sasswood, red ironwood, and Cassipourea firestoneana trees, with meticulously arranged rows of rubber trees. [39] Tapping operations commenced shortly thereafter, and by 1940, Firestone had achieved a production of over 7,000 tons of latex per year. [40]
Palaquium gutta. Gutta-percha is a tree of the genus Palaquium in the family Sapotaceae, which is primarily used to create a high-quality latex of the same name. The material is rigid, naturally biologically inert, resilient, electrically nonconductive, and thermoplastic, most commonly sourced from Palaquium gutta; it is a polymer of isoprene which forms a rubber-like elastomer.
Rubber latex is extracted from rubber trees. The economic life of rubber trees in plantations is around 32 years, with up to 7 years being an immature phase and about 25 years of productive phase. The soil requirement is well-drained, weathered soil consisting of laterite, lateritic types, sedimentary types, nonlateritic red or alluvial soils.
