In this paper, the resistance temperature properties of the complex conductive silicone rubber filled with carbon black were studied. The change of the resistance of conductive silicone rubber during the process by rising temperature was analyzed, and the influences of the content of fillers on the resistance temperature properties of the complex conductive silicone were studied in detail. The specific resistivity changes during the different anneal temperature and the resistance relaxation time with pulling force were measured , the influences of the thermal treatment and the content of conductive fillers on the mechanism of the resistance properties were also analyzed.
