The thermal conductivity of silicone rubber is higher in comparison with common organic rubbers. Hence the thermal conductivity increases by a few percent in the range 0 to 100 o c. When the material contains a high amount of inorganic fillers the conductivity can be improved twice which makes the material adequate for thermal interface sheets and heating rollers.

Silicone rubber unfilled 0 2 glass 1 1 stainless steel 15 aluminium 220 table 1 thermal conductivity of common substances as can be seen a typical unfilled silicone rubber has a thermal conductivity of approximately 0 2 w m k and even a highly filled silicone elastomer can barely exceed 0 4 w m k. Considering the relatively low thermal conductivity of the al2o3 filler as compared with cnts the rise of the thermal conductivity of the composite rubber successfully demonstrates the synergistic effect of the two fillers at a given. As the thermal conductivity of sir is very low the heat is accumulated in the discharge area and cannot spread quickly which will gradually. For thermal management arlon 0 63 2 5 1.

The alumina mps g phms pdms silicone rubber 500 10 90 composite had the thermal conductivity of 1 68 w m k and the tensile strength of 3 17 mpa exhibiting 18 3 and 84 3 enhancement. For many years the.
