Ultra High Thermal Conductivity Thermal Pad
Ultra high thermal conductivity silicon pad is a high-performance heat conduction interface material, which is made of imported raw ma terials. It is used to fill the air gap between the heating device and the he at sink or metal base. Their flexible and elastic characteristics enable it to cover completely uneven surfaces. The heat is transferred from the sep arated device or the whole PCB to the metal shell or the diffusion plate, which can effectively improve the heat dissipation performance and the efficiency and service life of the heating electronic components.
Features
- Excellent thermal conductivity, high thermal conductivity, low thermal resistance.
- High fit, soft and elastic.
