To make filler loaded conducting rubber which has excellent electronical and physical properties, CR and NBR were mixed with barium ferrite(BaO.6Fe2O3). From the result of this study, vulcanization characteristics shows that curve is upgraded as the filler concentration increases and CR has higher torque than NBR. In physical properties, elongation being higher, modulus comes to decrease. Tear strength gradually decrease after showing the maximum point when is in the 100phr in CR. Resilience is not good to cause the increase in filler concentration. In electrical properties, conductivity becomes low when filler concentration increase. The increase of voltage makes a conductivity grown, but the rate change is weak. The influence of temperature hardly changes on increasing temperature. The morphology and the dispersion of a conductivity filler in vulcanizates through SEM were good. The more filler concentration increases, the shorter the particle interval is.
