In a trial to obtain rubber vulcanizates with improved thermal properties, butyl rubber (IIR) loaded with 20 phr BaTiO{sub 3} was mixed with 100 phr of carbon black. In this case different types of carbon blacks, namely HAF, GPF, SRF and LAMP black were used. Electrical conductivity measurements of vulcanized samples were carried out at different applied electric power. The temperature (T) produced as a result of Joule heating effects as a function of time (t) was recorded. It was found that (T-t) characteristics markedly depend on the presence of barium titanate as well as the type of carbon black. Theoretical treatment of the obtained results was carried out.
