How is rubber manufactured?
Natural rubber is made by extracting a liquid sap, called latex, from certain types of tree. These trees are native to South America but are today commonly found in Southeast Asia. Latex is gathered from the trees by making a cut in the bark and collecting the runny sap in cups. This process is called tapping.
How was the first rubber made?
History. The first use of rubber was by the indigenous cultures of Mesoamerica. The earliest archeological evidence of the use of natural latex from the Hevea tree comes from the Olmec culture, in which rubber was first used for making balls for the Mesoamerican ballgame.
Where does the rubber for car tires come from?
Natural rubber, one of the primary materials in tires, is produced from the latex of para rubber trees (*1), and currently about 90% of its plantations are concentrated in Southeast Asia.
How rubber is made step by step?
Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and …

When was rubber first used?
Rubber – History of Rubber First identified and collected in Central and South American in about 1600 B.C.E., the earliest rubber was mainly used for games. Harvested from a plant, these ancient peoples formed balls with the substance, and used these balls for primitive bouncing games.
Who invented condoms?
Charles Goodyear, the inventor, utilized vulcanization, the process of transforming rubber into malleable structures, to produce latex condoms.
How did Charles Goodyear make rubber?
Charles Goodyear, (born Dec. 29, 1800, New Haven, Conn., U.S.—died July 1, 1860, New York City), American inventor of the vulcanization process that made possible the commercial use of rubber. In 1839 he accidentally dropped some India rubber mixed with sulfur on a hot stove and so discovered vulcanization.
Where does Goodyear get its rubber?
NATURAL RUBBER SOURCING More than 99% of the world’s natural rubber is made from latex derived from rubber trees, which are primarily sourced from Southeast Asia. The tire industry uses approximately 70% of the world’s natural rubber, and demand for natural rubber is growing.
What is rubber production?
Rubber Production. Rubber Production: Tapping rubber trees, latex collection and processing of raw rubber. Many plants produce latex, which oozes from cuts and injuries as a milky sap. Some latexes are collected for their resins or their alkaloids (opium). Rubber is a coagulated, elastic latex.
Who invented erasers?
3. Erasers were invented by accident. Though Joseph Priestly may have discovered rubber’s erasing properties, it’s the British engineer Edward Nairne who is generally credited with developing and marketing the first rubber eraser in Europe.
Who invented rubbers?
Where did the origin of rubber come from?
Ancient Rubber. The exact origin of rubber is not known. The indigenous people of the Americas had known and used rubber long before the arrival of European explorers. Rubber makers in ancient Mesoamerica were almost 3,500 years ahead of Charles Goodyear and his vulcanized rubber.
What’s the best way to make a rubber band car?
You can also build a bunch of rubber band cars and race them to find out which one is the best! Paint a sturdy, 12-inch (30.48-centimeter) cardboard tube. Pick a tube that’s sturdy, like the kind found in rolls of aluminum foil.
When did synthetic rubber start to be used in tires?
The 1920s saw the development of tire materials. The DuPont Company industrialized synthetic rubber in 1931, allowing the increase in tire production, which used to be dependent on natural rubber. Synthetic rubber ushered in a turning point in tire production.
What’s the percentage of tires made of natural rubber?
By 1993 natural rubber had recaptured 39 percent of the domestic market. Today nearly 50 percent of every auto tire and 100 percent of all aircraft tires are made of natural rubber.
