Silicone rubber/carbon iron powder composite was physically modified by adding hexagonal boron nitride (h-BN) through melt blending, and the effects of h-BN on the mechanical properties, magnetic permeability, thermal conductivity, and thermal ageing properties of the composite were analyzed. The results show that h-BN well distributes in the composite, and it has good compatibility with silicone rubber matrix. The introduction of h-BN can effectively increase the tensile strength of the composite, while decrease the magnetic permeability. When the adding amount of h-BN is more than 20 phr, the thermal conductivity increases effectively. Under the continuous thermal ageing, the tensile strength of the composite increases at first and then decreases, while the elongation at break decreases continuously.
