Thermal conductivity silicone rubber.

For thermal management arlon 0 63 2 5 1. 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. Silicone rubber has good electrical properties antiaging performance and can operate in the long term under a strong electric field and withstand various kinds of natural erosion. The thermal conductivity of the al2o3 cnts sr composite is 105 49 higher than that of neat silicone rubber.

Hence the thermal conductivity increases by a few percent in the range 0 to 100 o c. For many years the. However it should be noted that an increase in temperature might result in a decrease in thickness influencing not the thermal conductivity but certainly the thermal resistance. Silicone rubber can be immersed in water cold water warm water boiling water for long periods with water absorption of about 1.

The thermal conductivity of silicone rubber is higher in comparison with common organic rubbers. 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.
