The surface of thermal silica sil pad is flat and smooth. It has good adhesion to the surface metal and ceramic base materials. With high thermal conductivity, it can achieve low thermal resistance under relatively low pressure.
Characteristic
High thermal conductivity, low thermal resistance
High AC voltage value
Smooth surface
Strong pressure resistance, wear resistance
Non-sticky surface
