3M 5510 is a acrylic based thermally conductive gap pad. Compared with traditional thermal silicone pad, it is a little harder. Because of innovation concept limitation, most of customers tend to design thermal silicone pad for applications except some optical devices such as camera, LED light or car headlights which requires no siloxane contained.

The thermal conductivity of 3M 5510H is 2.0W/mK(test standard is 3M’s own standard, if tested by ASTM D5470, 3M 5510H’s thermal conductivity is 1.6W/mK only. Whatever, we don’t care. Whether it is real it or not, it’s up to customer), but GLPOLY XK-PN20 which is similar to 3M 5510H was t ested by ASTM D5470. XK-PN20 non-silicone thermal pad has a 2.0W/mK of thermal conductivity. It shows that GLPOLY non-silicone thermal pad provides better performance than 3M 5510H.

As we mentioned, acrylic based thermal pad is a little hard, it’s hardness is Shore00 50. GLPOLY XK-PN20’s hardness is Shore00 40, though the value difference is not big,  but in application, compression rate may be remarkable under the same forces, maybe it’s a key element for customer to make choice.

Does non-silicone thermal pad have any weakness? The application temperature of silicone free thermal pad is much low than thermal silicone pad. usually, we just apply non-silicone thermal pad to devices which its upper temperature limit is under 125℃. So, before selecting, we must know about both designs and materials.

If you are inconvenienet to get 3M 5510H or you want to reduce cost, you can select GLPOLY XK-PN20 silicone free thermal gap pad.  With GLPOLY, we’ll always offer you a better choice and solution.

GLPOLY has partnered with top brands such as Huawei Marine, dJI, NIO Auto etc, providing quality thermal interface materials.
