Rubber Industry  Background

Basically can be derived from natural rubber from the sap of the rubber tree(Or known as latex), and the production of human (synthetic). When the wounded rubber tree, the sap produced will be so much more. The main source of latex rubber is the rubber tree Hevea brasiliensis (Euphorbiaceae). Asia is currently a source of natural rubber. Rubber beginning to live only in South America, but now it is successfully developed in Southeast Asia. The presence of rubber

in Southeast Asia thanks to the services of Henry Wickham. this time, Asian countries produce 93% of natural rubber production, which is Thailand's largest, followed by Indonesia, and Malaysia.When Christopher Columbus and his entourage discovered America in 1476, they are amazed to see the ball played by the Indians who can rebound when dropped to the ground. This is where the rubber starts history, but only in the year 1530 there is a written report on Gummi optimum, called Pietro Martire d'Anghiera for rubber. The ball was made of a mixture of roots, wood, and grass, mixed with a material (latex) and then heated above the bed and rounded like a ball. Oran Indian ball can bounce higher than a ball made of common people of Europe at that time. In 1615 a writer, F.J. Torquemada Mexico reported that the Indians made of waterproof shoes or rubber latex material. Fresnau a French expert reported that many plants that can produce latex or rubber, of which the type of Hevea brasiliensis, which grows in the Amazon jungle in Brazil who is now a major rubber-producing plants and is cultivated in Southeast Asia is a major rubber producer in the world today .

In 1770, the English chemist, Joseph Priestly, reported that the rubber can removes pencil marks. In 1775 the rubber began to be used as a pencil eraser, and be written in the British rubber called by the name of rubber (from to rub). Rubber goods that are produced when it has always been stiff in winter and sticky in summer. Many experiments have been performed to obtain the properties of rubber are not affected by the weather. A year later, N. Hayward found that when sulfur is added to a solution of rubber or rubber is applied to the seed of sulfur, will cause the rubber to dry faster.Thomas Hancock writes in his book published in 1985 that in 1842, Brockedon showed him a piece of rubber samples are from the U.S. are not affected by weather or by the oil. Thomas Hancock saw that the piece was a little

yellowish on the inside and smelled of sulfur. This change process and patented in 1843 and according to his proposal, Mr. Brockedon, this process is called vulcanization, which later the name was accepted in Britain, America and the world at large until now.Before that in 1838, Charles Goodyear in America has been engaged in research using a sulfur compound, and heat to obtain a rubber compound that is not affected by the weather, as evidenced by letters received from some people who see or receive the results of experimental rubber samples in 1839. New in 1844 he obtained a patent for his invention. From some writings that discuss the discovery of vulcanization, and based on Hancock's own writings stating that Brokedon meperlihatkan examples from American rubber which is not affected by the weather, most authors agree that the first inventor vulkanisai process should be granted to Charles Goodyear. GovernmentU.S. to encourage research and production to produce synthetic rubber to meet the urgent needs. This great effort resulted in a short time and continues to grow

after the end of the second world war, third world consumption of rubber is synthetic rubber.Enough to dominate synthetic rubber rubber industry, but the use of natural rubber is still very important today, among others, military and automotive industries.In 1983, nearly 4 million tons consumed by the world's natural rubber, synthetic rubber that is used but has been more than 8 million tons.
