Thermal silica grease is a new kind of silicone with additives of high thermal conductivity. As a superior insulation, the thermal conductivity of silicone rubber is usually only about 0.2W / (m • K), but by adding a high-performance heat-conductive additives (e.g. Al, Cu, MgO, AIN, BN, SiC, graphite, carbon black, etc.), the thermal conductivity can be improved several times or even several tens of times.  

The thermal conductivities of several thermal silica greases with different additives were measured by the TC3000 meter and listed in table 1. The results show that there is a significant difference of the thermal performance for different sample. Besides, TC3000 shows its advantages when used in sample with irregular shapes.
