As lightweight design becomes more and more important in the automotive industry, an increasing amount of aluminium and magnesium parts is used in combination with steel for body constructions. Because of the variable electrochemical potential of these metals corrosion problems can take place especially where parts of the different materials make contact by electrically conducting rubber sealings. To overcome this problem of electrochemical corrosion, the usage of special soft blacks is necessary in order to increase the electrical resistance of the applied sealing rubber compounds. As a consequence the influence of structure and specific surface area of carbon blacks on the electrical behavior of filled rubber compounds is of great interest and is investigated in detail. Furthermore accompanying dynamic stress-softening measurements (Payne effect) are carried out. The findings are related with electrical resistance behavior to obtain more basic information about the influence of the nature of carbon blacks on this subject.
