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.
Conductivity is the inverse: For example, rubber is a material with large Ï and small Ïâbecause even a very large electric field in rubber makes almost no current flow through it. On the other hand, copper is a material with small Ï and large Ïâbecause even a small electric field pulls a lot of current through it.
