What are the elements of rubber?

What is rubber farming?
Rubber Plantation. Introduction of Rubber:- Basically rubber is an elastic solid material retrieved from latex of many tropical trees. However, “Hevea brasiliensis” is the most commercially cultivated rubber plant. Rubber is used for many purposes which may include erasers to tyres, tubes & industrial products.

What is rubber culture?
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.
How do you increase the yield of rubber?
Latex flow during tapping of the rubber plant Hevea brasilensis is the crucial parameter for rubber yield. The extent of latex flow depends on water circulation in the tissues surrounding the latex-producing cells. Water, and therefore latex flow, can be stimulated by ethylene or auxin treatment of the bark.

What are the properties of natural rubber?
Natural rubber has certain unique properties such as follows:
- Natural rubber combines high strength (tensile and tear) with outstanding resistance to fatigue.
- It has excellent green strength and tack which means that it has the ability to stick to itself and to other materials which makes it easier to fabricate.
Why is it called a rubber plant?
Rubber plants earned their name thanks to their sap, which is sometimes used to make rubber. The rubber plant’s leaves also have a shiny and rubbery appearance.
