UTP-20 thermal pad is a very cost-effective general economic thermal gap filling gasket, soft with its own micro-stick, easy assembly. Under low compressing force to show good thermal conductivity and electrical insulation properties. Bedding on the gap between the heat device and the heat sink or the machine shell to extrude air to reach the full contact forming a continuous thermal conduction. Using heat sink or machine shell as a cooling device can effectively increase the cooling area to achieve a good cooling purposes.
