5~8w/m-k silicone thermal conductive pad

Item No.: UHTP
Ultra-high conductive with 5~8w

         UHTP series are ultra-high thermal conductivity silicone pad with 5w/m-k~8w/m-k high-performance thermal conductivity interface material,which selecting 100% importing raw materials to fill the the air between heating device and heat sink or metal base.Its softness and flexibility make it can be used covering a very uneven surface.Heat transfer from the separation device or the entire PCB conduction to the metal shell or diffusion plate to improve the overall heat dissipation and improve the efficiency of heating electronic components and service life.

1.The original size is 200mmx400mm, 300mmx400mm and it is decided by the machine.However, it can die-cut to any size by machine again. So we can offer you the different size you need.

2.As for color, the general is grey.If you need other color,please tell me.

3.As for thermal conductivity,if you need others,also please let me know.


Features and advantages

1.Ultra-High thermal conductivity,low thermal resistance;
2. Soft and flexible to reduce the thermal resistance of interface;
3. High electrical insulation,protecting the sensitive electronic components;
4. ROHS UL compliant




Step 1

Clear the surface where you are going to paste the thermal pad; 




Tear the protective film of one side and remember do not tear the protective film of both sides in the same time to reduce the contact times and scare of the thermal pad avoiding the damage of thermal pad stickiness and thermal conductivity. 



Paste the side without protective film on the products, then tear the other side protective film, then install your electronic components on the thermal pad. After installation, press slightly and let it stay for a while to ensure the thermal pad fixed well.
