Effect of pre‐extension on the electrical conductivity of styrene‐butadiene rubber loaded with FEF carbon black. II. Electrical conductivity in transverse direction

Continuing the previous work, the electrical conductivity, σ, of 70 phr FEF/SBR pre‐extended samples in the transverse direction is discussed in detail. The pre‐extension is a parameter which affects the anomalous behaviour which appeared as a minimum in the electrical conductivity σ vs. T curves. A correlation between the effect of pre‐extension on both the logitudinal and transverse direction has been done. The dielectric constant, ϵ′ and the dielectric loss, ϵ″, of the above mentioned pre‐extended sample in the transverse direction and their dependence on temperature was observed.
