Abstract The practically magnetorheological rubbers were fabricated, and the influence of carbonyl iron powders (CIPs) contents, carbon black contents, softeners contents and modified CIPs by different coupling agent on the physical and mechanical properties and the magneto-rheological performance were investigated in this paper. The results show that for the magnetorheological rubbers made from the NR/SBR blend, the samples with 300 phr carbonyl iron powders, 40 phr carbon black, 15 phr softeners and utilizing silicane coupling KH-570 modifying CIPs have the best physical and mechanical properties and the best MR effects. It results from the comprehensive effects of modifying by coupling with the reasonable structure, strengthening by the carbon black and toughening by the softener, etc.
