What is heat conduction sealing silicone

Heat transfer sealing silicone is a special silicone material for electronic equipment and heat dissipation system, used to provide sealing and heat insulation between the heat dissipation components to protect the equipment from the external environment and temperature.

Since the air is a poor conductor of heat, it will seriously hinder the transfer of heat between the contact surface, and the heat dissipation sealing silicone between the heat source and the radiator can squeeze the air out of the contact surface. With the addition of heat dissipation and heat conduction sealing silicone, the contact surface between the heat source and the radiator can be better and fully contacted, and the face-to-face contact can be truly achieved. The reaction in temperature can be as small as possible.
