A glimpse of the history of rubber plants

The rubber plant comes from the Latin called Hevea braziliensis. Rubber plants were first discovered in the Amazone river valleys (Brazil). When Christophel Columbus discovered the American continent in 1476, he was astonished to see locals (Indians) playing ball with a material that could bounce when dropped to the ground. The ball is made of a mixture of roots, wood, grass, and materials (latex) which is then heated over a fire and rounded into a ball. Long before these rubber plants were popular, indigenous people in different places like the United States, Asia and South Africa used other trees that also produced sap. This sap is produced from the plant Castillaelastica (family moraceae). The plant is not utilized anymore because it lost more than rubber. In Indonesia alone rubber plant tried cultivated in 1876 in the first planted in Bogor Botanical Garden.

This rubber plant when scratched / slashed on the bark of the stem will release a white liquid called latex. This will dry and clot if left for more than 2 hours. This new rubber tree may be harvested (to be taken latex) after the age of 5 years and has a productive age of 25 to 30 years. Latex this will then be processed into a new form (product finished goods). Latex that is still in the form of liquid into raw materials for toy rubber balloon products, chewing gum, rubber gloves, condoms and others. While latex that has been dry (frozen, often called kompo) into raw materials of car tires, conveyor belt, rubber protector on the car body, and others.
