How Thermally Conductive Gap Filler Pad Boosts Performance of Electronics

The thermally conductive gap filler pad is a thermal conductive material synthesized by a special process with silica gel as the base material, adding some metal oxides and other auxiliary materials. Thermally conductive gap filler pad is a heat dissipation product specially designed for heat transfer in the gaps of electronic products. It fills the gaps to transfer heat between the heat-generating parts and the heat-dissipating parts, and plays the role of insulation, shock absorption and sealing.

Why choose thermally conductive gap filler pad?

1. The main purpose of selecting thermally conductive gap filler pad is to reduce the contact thermal resistance generated between the surface of the heat source and the contact surface of the heat sink, and the thermal pad can fill the gap between the contact surfaces well;

2. Air is a poor conductor of heat, which will seriously hinder the transfer of heat between the contact surfaces, and installing a thermally conductive gap filler pad between the heat source and the radiator can squeeze the air out of the contact surface;

3. With the addition of thermally conductive gap filler pad, the contact surface between the heat source and the radiator can be better and fully contacted, and face-to-face contact can be truly achieved, so that the temperature response can be as small as possible.
