Self vulcanizing?

Any vulcanizing I have done in years past involved patching a tire from the inside and lighting a compound on the patch with a match. When the compound had melted to the inside of the tire you blew out he flame. This made a bullet proof seal! Vucanizing involves the application of heat. How does a plug self vulcanize?
