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.
What Rubber is Made From Rubber is just a combination of polymers of isoprene units and other natural substances and impurities. It is a build up of the isoprene unit molecules and is not normally made up of other synthetic materials (although sometimes these materials are used to sythesise rubber).Natural rubber comes from the sap of the rubber tree.Today's rubber is mostly a synthetic, formed from substances like latex. jb answer real rubber comes from the sap of the rubber tree. synthetic rubber does not come from latex, but is made from oil.oday's rubber is mostly a synthetic, formed from substances like latex. jb answer real rubber comes from the sap of the rubber tree. synthetic rubber does not come from latex, but is made from oil.
