Silicone free thermal pad Bergquist Gap Pad 2200SF and GLPOLY XK-PN20

What features does Bergquist Gap Pad 2200SF have? In general, we can get three features from the introduction. Firstly, silicone free material based which is suitable for silicone sensitive equipments, secondly, it’s high comformable, optimizing contact between heat generator, thermal pad and heat sink, thirdly, fiberglass reinforaced for easy handling.

From above description, I don’t think there is any threshold of advanced techology which stopped other manufacturer. GLPOLY, a chinese thermal interface materials supplier who is at cutting-edge of silicone free thermal materials development for ten years, can provide alternatives effortlessly, we will take Gap Pad 2200SF and GLPOLY XK-PN20 for an example.   

Gap Pad 2200SF and XK-PN20 are medium performance silicone free thermal pads with 2.0W/mK of thermal conductivity. Though the thermal conductivity of both materials are the same, the performance is not the same. Why? Because the thermal resistance is different. We can see that Gap Pad 2200SF’s thermal resistance is 0.43℃in2/W and XK-PN20’s thermal resistance is only 0.37℃in2/W, GLPOLY XK-PN20 silicone free thermal pad will provide better performance.

How about is the physical property? We check the hardness of both materials. We know that if a thermal pad is softer, it will provide better contact.  GLPOLY XK-PN20’s hardness is Shore00 40, it offers high conformability at low clamping forces.

If you aer seeking for a cost effective silicone free thermal pad which is alternative to Gap Pad 2200SF, GLPOLY silicone free thermal pad XK-PN20 would be a good choice.
