Thermal pad(Thermally conductive silicone Pad) combine high thermal conductivity with specific organic properties of heat resistance and electrical insulation. Thanks to that, thermal pad effectively transfer heat to heat sinks or outer space from heat generating components. In computing and electronics, thermal pads are commonly found on the bottom side of heat sinks to aid conduction of heat away from the component being cooled (such as a CPU or another chip) and into the heat sink (usually made from aluminium or copper).
Thermal Tape(adhesive) material has adidtional properties such as flame retardant grade(Ul94-V0 and halogen free), good weather and heat resistance.
Thermal Grease compound is designed to provide a preferential heat-transfer path between heat-generating components and heat sinks or other cooling devices like fans, heat spreaders or heat pipes.
