The Silicone Thermal Pads work as the good gap filler and bridges uneven surface and gaps. The pads are installed between the heatsink and the device which are designed to improve the thermal transfer to the heatsink. Size:100mm x 100mm x 1 mm (L x W x T); Thermal Conductivity: 1.5 w/m-K; Withstand Temperature: 50~200(°C); Color: Gray. The Thermal Pad is made of silicone with low hardness, which has the effect of damping and cushioning, and at the same time has good compressed. Installation steps: 1. Clean the surface of components first; 2. Then tear off the plastic protective film; 3. Place the thermal pads where needed. Please choose the soft silicone thermal conductive pads according to the required thickness and size.
