One of the most important global issues facing us today is the reducing of synthetic rubber waste and one of the solutions to this problem is the use of polyisoprene, which is biodegradable and recyclable. Polyisoprene, known as natural rubber, is obtained from the latex harvested by slicing the bark of the rubber tree. It is an elastic material with unique physical properties such as: high electrical resistivity (being a very good electrical insulator), good chemical resistance and excellent water resistance. Natural rubber also exhibits very important mechanical properties, such as very good abrasion resistance, very good tear resistance, very good resistance to tensile, compressive, bending and torsional stresses, excellent resilience and the ability to deform very long without spoiling. The natural rubber is one of the most important polymers for our society. It is a very useful material from an industrial point of view due to its properties and it is used in a wide range of applications such as tire production, transmission belts, oil hoses, gaskets and so on. Although natural rubber is both a renewable resource and an extremely versatile material, there are certain needs that it cannot meet, which is why the petroleum-based synthetic rubber was invented. In general, synthetic rubber is better than natural rubber in terms of temperature resistance, abrasion resistance and a much longer lifetime. The shelf life of natural rubber is 3-5 years compared to that of the synthetic rubber which is 3-10 years. In this case, the shelf life refers to the time limit within which the rubber retains its quality and properties, being able to be used in certain applications, but its lifetime is much longer before the final degradation, in general, being influenced by a series of factors such as: exposure to sunlight, exposure to extreme temperatures, improper storage under recommended conditions, manner of use, rubber composition, material quality and natural aging. The signs that characterize the degradation of natural rubber are the appearance of cracks, yellowing, loss of elasticity and its excessive hardening, as well as a decrease in adhesion to its surface. Thus, to improve the resistance of the rubber and increase its lifetime, the process of vulcanization or the mixing with additives in the process of its manufacturing are applied, subsequently it being able to be used in a much wider range of applications.
