The effect of different contents of bis-triethoxysilylpropyl tetrasulfide (Si69) and bis(tert-butylperoxy diisopropyl) benzene (BIBP) on vulcanization characteristics, mechanical properties, and electrical insulation property of EPDM were compared and analyzed. The results show that with the increase of Si69 and BIBP content, the curing speed increases, the process positive curing time decreases, the maximum torque increases, the crosslinking density of the rubber increases and the mechanical properties are improved. With the increase of Si69 content, the electrical insulation property of the rubber decreases; with the increase of BIBP content, the electrical insulation property of the rubber increases gradually.
