AM thermal silicone sheet is a universal and economical thermal sealing gasket with high cost performance, soft, self-adhesive and easy assembly.It shows good thermal conductivity and electrical insulation performance under low-pressure compression force. It paves the gap between the heating device and the heat sink or the machine shell, extrudes air to achieve full contact, and forms a continuous heat conduction channel. Using the heat sink or the machine shell as the heat sink, the heat dissipation area can be effectively improved, so as to eff ectively improve the heat dissipation effect.
