In many cases, the first question we got when we received call from customer was “how much is the thermal pad?”. actually, it is not easy to answer immediately. Why? Because there are some factors affecting price.

Firstly, thermal conductivity would be considered priority, it is a major factor to fix price. For example, price of a thermal gap pad with a thermal conductivity of 8.0W/mK will be dramatically different from the one with a thermal conductivity of 11.0W/mK. Maybe you think it is small gap by 3.0W/mK, but they will be achieved by using different materials or technique.

Usually, we use aluminum oxide as thermally conductive filler for 8.0W/mK thermal pad, however, boron nitride will be used in a 11.0W/mK thermal gap pad. There is huge difference between these two raw materials. Now, GLPOLY thermal pad XK-P110 with 11.0W/mK is in volume production, we are developing higher performance thermal interface materials with 15W/mK or 17W/mK, aimed for Fujipoly SARCON XR-Um which provides the highest 17.0W/mK of thermal conductivity.

Secondly, hardness is a considered factor too. A ultra soft thermal gap pad is more conformable to the component topography, making contact tightly and optimizing heat transfer. If high performance will be achieved, more thermally conductive filler must be used. Here is the contradiction, the more thermally conductive filler used, the higher hardness became. So we need to use high quality silicone oil and process to control the whole progress.

Last but not least, we provide quality service as follow 1) short lead time by 3-5 times faster than average, 2) no mould for normal product that will be finished by digital cutting machine saving cost and time, 3) wooden case or frame will be used for avoiding damage in transport. More information you collected, more precise offer you received.

GLPOLY had collaberated with LG, GAC NE Auto, NIO Auto, Lixiang Auto, Freetech Auto Pilot, dJI Drone etc., providing advanced thermal interface materials and superior service.
