With a rapid development in recent years, GLPOLY has made great achievement, providing non-silicone thermal gap pad competitive with world class brands.

GLPOLY is always at the leading edge of technological development of non-silicone thermal pad. But the reality was that many engineers knew about imported non-silicone thermal gap pad and have no idea about the high quality silicone-free thermal pad supplied by domestic suppliers, like GLPOLY. Here we took 3M 5500H as an example, checking out comparison between GLPOLY non-silicone thermal gap pad and 3M 5500H thermal acrylic gap pad.

Generally, performance of thermal gap pad was judged by thermal conductivity and thermal impedance. Two test methods were used for determining thermal conductivity, in-house test method and ASTM D5470. 3.0W/mK of thermal conductivity was determined by 3M in-house test method and 2.0W/mK was determined by ASTM D5470. So we could  calculate 3M 5500H providing a thermal impedance of 0.83℃in^2/W. From professional perspective, this value of thermal impedance was a little higher and it reduced thermal performance.

GLPOLY non-silicone thermal gap pad was tested by ASTM D5470,resulting in 3.0W/mK which is more reliable than 3M 5500H. Furthermore, 0.2℃in^2/W of thermal impedance of GLPOLY XK-PN30 is much lower than that of 3M 5500H. Obviously, GLPOLY XK-PN30 provided more exceptional performance than 3M 5500H did.

Also, hardness is significant factor to performance of thermal gap filler pad. the softer one was much conformable and provided better thermal contact than harder one. With a hardness of Shore00 50, GLPOLY XK-PN30 non-silicone thermal gap pad offered a higher compression rate, conformance and effective thermal contact comparing with 3M 5500H’s hardness of Shore00 65.

Generally speaking, GLPOLY non-silicone XK-PN30 can substitute for 3M 5500H completely, for detail please contact GLPOLY.

GLPOLY non-silicone thermal gap pad was applied to Huawei Marine, DT mobile etc. with high reliability and superior quality.
