Isoprene Rubber

The most common chemical elements in rubber are carbon (c) and hydrogen (H). The Polymers of natural rubber are mainly built of these elememts. In synthetic rubber these elements are products from the petrochemical industry.
A tree with a good yield could give 30 to 35 grams of rubber per day the contents of cups are emptied to the containers and transported to a rubber factory. Acetic acid is added to promote coagulation. To manufacture smoked sheets, the rubber is made into sheets in a mill, washed dried and smoked and finally classified. With the exception of Butadiene rubber, natural rubber has the best elasticity of all rubber types. It has very good resistance to abrasion and fatigue .Among the drawbacks are the materials poor resistance ozone (weather) and oils and fuels.
Natural rubber is mainly used in the production of heavy duty tires , vibration dampers, springs and bearings. For special purposes it is used in hoses seals , conveyor belts, coated fabrics and other products.
