Organic rubber ยางพารา ยางพารา ยางพารา, also called India Rubber or caoutchouc, is an elastomer (an elastic hydrocarbon polymer) that was originally derived through latex, a milky colloid made by some plants. The plants will be ‘tapped’, that is, an incision made into the bark of the tree and the actual sticky, milk colored latex sap accumulated and refined into a usable rubber. The purified type of natural rubber may be the chemical polyisoprene, which can additionally be produced synthetically.

The seedlings were then provided for Ceylon (Sri Lanka), Indonesia, Singapore and Uk Malaya. Malaya (right now Malaysia) was later being the biggest producer of rubber. About 100 years ago, the Congo Free of charge State in Photography equipment was also a substantial source of organic rubber latex, mostly gathered by forced labour. Liberia and Nigeria additionally started production regarding rubber.
In India, commercial cultivation regarding natural rubber was introduced by the British planters, although the experimental efforts to develop rubber on the commercial scale in India were initiated as early as 1873 at the actual Botanical Gardens, Calcutta. The first business Hevea plantations in India were proven at Thattekadu in Kerala in 1902. In the nineteenth and early 20th century, it was categorised as “India rubber. ” In 2010, India’s natural rubber consumption stood at 0. 978 million tons annually, with production at 0. 893 million tons; the rest was imported having an import duty regarding 20%.
