Thermal conductivity
The thermal conductivity of silicone rubber is about 0.2W/mヘ·K, a value higher than that of common organic rubbers. Some silicone rubbers contain a high proportion of special inorganic fillers to improve thermal conductivity (about 1.3 W/mヘ·K), and these are used to make products including thermal interface sheets and heating rollers.
