High conductive soft silicone rubber thermal pad with 2w~4w

Item No.: HTP
Hight conductive 2~4w/m-k

         HTP series are thermal conductive silicone pad with high thermal conductivity. The raw material is from Japan Electric Denka (Denka) which made of high thermal conductivity spherical alumina powder and Dow Corning polymer, which is a cost-effective thermal filler.Natural micro-viscosity and softness of surface is good for filling the air gap to complete the heat transfer between the heat source and heat sink improving the thermal conductivity It is very suitable for high performance requirements and is a very good thermal interface materials.

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 and blue.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.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.
