Natural rubber (NR) is among the most important elastomers used
in the manufacturing of rubber products such as tires and conveyor
belts. Many reviews were devotedto understanding the chemical,
physical as well as compounding properties of NR[1–4]. NR is a
material that is capable of rapid deformation and recovery, and it is
insoluble in a range of solvents, though it will swell when immersed
in organic solvents at elevated temperatures. Some of its many
attributes include abrasion resistance, good hysteretic properties,
high tear strength and high tensile strength. It can show poor tire
performance in areas such as traction of wet skid when compared to
synthetic elastomers such as styrene butadiene rubber (SBR). In some
rubber items, natural rubber used alone does not have sufficient
strength to withstand the forces encountered by the article during its
use in applications. For example, in tires, belting and hoses, it is
necessary to increase the strength of the rubber by incorporating
either textile or steel reinforcement. For many applications, it is
