Typical epichlorohydrin rubber grades were prepared and their electroconductivity was investigated. The vulcanizates of this rubber show volume resistance values of 10(7)-10(10) Omega cm, depending on the grades. Moreover, the electroconductivity depends on the cure system used; the sulfur cure system leads to the lowest volume resistance. Furthermore, the influence of electrolytic salt, carbon black and other ingredients is shown. By a combination of various parameters the electroconductivity can be controlled in a wide range.
