About 500 years have passed since natural rubber was discovered by Columbus. Since then, the use of crude rubber has gradually spread in Europe and across the U.S.
With the advance in the method of processing rubber as well as in scientific research, Charles Goodyear has managed to discover the "heat curing method" in 1839, a process in which crude rubber is heated with sulfur to yield "vulcanized rubber", highly elastic and more resistant to heat than crude rubber. This process was eventually refined to become the famous vulcanizing process in the rubber industry. After perceiving the essence of this process and many developments were carried out and actually this was the starting point of modern rubber industry.
During the Industrial Revolution from 1830's through the follow decades, the primary goal was how to improve transportation of goods and passengers from one location to another. Therefore bicycles and automobiles were invented along with the opening of railway traffic, and then a necessity to meet the needs of the times has led to the invention and later to the spread of pneumatic tires which was certainly the most important invention in rubber industry.
In 1845 R. W. Thomson in England tried to develop pneumatic tires for trucks
to replace the tires mounted on iron wheels or solid tires prevalent in those
Later in 1888, Dunlop (J. B. Dunlop) in England succeeded in developing pneumatic tires for bicycles and tricycles with solid tires. The pneumatic tires invented by Dunlop were adopted in the bicycle race in 1889, and went so far as to be used for automobiles until finally they were standardized in around1905 after various improvements. Further to that, a session of studies and deep research was done in order to improve tire characteristics, especially in terms of technology and quality. When the risk in driving was came to public attention, safety regulations were introduced into manufacturing process and they are extensively implemented today in the tire and rubber industry. Later on, other physical considerations were taken into account in order to improve driving experience and safety. Significant alterations were performed accordingly in terms of structure, material, patterns, and shape and further in the method of testing tires.
As tire industry is an essential part of rubber industry, substantial progress has been carried out in the process of tires & rubber manufacturing.
This remarkable change, which involved replacing of old equipment and pursuing advanced technology, has led the rubber industry to meet the global demand for tire and technical products.
