Natural rubber is an elastomer and a thermoplastic. Once the rubber is vulcanized, it will turn into a thermoset. Most rubber in everyday use is vulcanized to a point where it shares properties of both; i.e., if it is heated and cooled, it is degraded but not destroyed.atural rubber is often vulcanized, a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity, and to prevent it from perishing. The development of vulcanization is most closely associated with Charles Goodyear in 1839.
Most of the rubber we see today comes from petroleum but about a third of industrial rubber comes from the natural source of the Rubber Tree. This tree is important because it contributes to the making of many rubber products such as shoes, balls, household items, and many other products we could not live without.ost of the rubber we see today comes from petroleum but about a third of industrial rubber comes from the natural source of the Rubber Tree.
