Beigquist Gap Pad Ultra VO Soft is the first chioce for automotive electroncis thermal management to many thermal management engineers. Most of Chinese suppliers can’t provide alternative except GLPOLY. Bergquist Gap Pad Ultra VO Soft has an extreme low hardness of Shore00 10, providing excellent compression. Many counterparts said they can provide alternative with similar thermal performance or electrical properties, but the most important features of low hardness and high compression will not be contrasted. Siemens engineer found us and asked ”Can you provide an alternative to Bergquist Gap Pad Ultra VO Soft, with same or better thermal performance, compression and thermal resistance?” . Actually, we had been developing a thermal pad which is with similar performance to Bergquist Gap Pad Ultra VO Soft, and we were almost there. So we told customer the truth”We are developing a similar product now, and we are going to complete it in half a month.”. Customer wish to wait for final test report, because the didn’t find a proper product yet. Half a month later, we finished the samples as expected. When I sent them the samples, I can feel they don’t value the samples. But after they finished the test, they were surprised, hardness of Shore00 10, compression of 90% and thermal resistance of 0.35℃in2/W…, thermal and physical properties were as good as Gap Pad Ultra VO Soft’s. “We had tested dozens of samples, your product is the best, also it’s only one that met our requirements.” GLPOLY XK-P10F is designed for auto eletronics with high performance, low thermal resistance. It provides low hardness and compression, optimizing interface contact and heat transfer. GLPOLY thermal management materials have been used in new energy vehicle battery pack.

Three years ago, thermal pad was a significant role, predominately in thermal management of EVs battery pack. With the advancement of EVs battery technologies, trend to shift away from thermal gap pad to thermal gap filler, providing a more closer contact between cells or cell and heat sink, and thermally conductive structural adhesive is the best in gap filler family. GLPOLY is the first one in China to develop thermally conductive structural adhesive for “cell to pack” battery pack in a new technology—modified epoxy which differ from existing PU technology. Consequently, we received many queries from engineers about properties of thermally conductive structural adhesives. Here I sorted out some information for your reference. Q: What’s the linkage between bond line thickness and shear bond strength? A: In practical application of “cell to pack” battery, there is no inevitable linkage between these two properties. Q: Shall the bonding strength vary with Al substrates? A: No matter Al3003, Al6063 or Al1030, the Al content is greater than 97%. It depends on the Hydrogen bond between crosslinker and metal atom. Effect affected by other factors is less than 3% which is within the range of tolerance. GLPOLY has full set of Al3003 fixtures for validating. Q: What factors shall affect shear bond strength? A: 1) Bonding strength decreases a lot if the surface of aluminum is oxidized to alumina; 2) Roughness. The rougher the surface, the greater the bonding strength; 3) Modifier applied on the surface. Depending on specific conditions. Q: Why not mark value of butt-joint bonding strength? A: A joint made by fastening ends together without overlapping. There is no need to test it because no butt joint happened between cell and water- cooling plate. Q: Why is it recommended to remove insulation painting? A: Painting increases thermal resistance. And in this case, it shows bonding strength between thermally conductive structural adhesive and painting, not adhesive and water-cooling plate. Furthermore, GLPOLY thermally conductive structural adhesive has electrical insulation. Q: Are contact thermal resistance the same between different substrates? For example, PET and Al? A: Both interface thermal resistance of PET and Al are between 0.000178~0.000679, but the contact thermal resistance is hard to test. our specification comforms to the result of nearly 300 regression tests. The contact thermal resistance is negligible due to extremely low value. By extension, the above conclusion is true in the application of soft pads. So it is true for liquid thermally conductive structural adhesive if there is no air bubble or water film. If you have any other question, please feel free to contact GLPOLY for detail.

It is easy to produce thermal gap pad, but to be honest, there are just a few of manufacturers who can produce quality thermal gap pad, GLPOLY is one of them. Why do I say it is easy to produce thermal gap pad? The main contents of thermal pad are similar, you can make primary product easily with some additives. Why is it hard to make quality product? because of different grade of raw materials, different batching accuracy. They are vital to thermal and physical properties. Counterparts will mislead customer paying attention to a specific parameter, ignoring other parameters. A pioneering thermal management solution supplier will never do this. GLPOLY provides customers with customized thermal materials as requested. An ltalian auto component supplier, the engineer gave me two instructions when he found us 1) thermal conductivity is not less than 2.0W/mK, 2) Compression is as big as possible. He did not give a specific vulue to compression that makes it difficult to satisfy. This thermal pad was going to be applied in electric vehicle battery pack, so we recommended a compression of 40% according to our experiences. After test, customer fed back the compression is not enough with 700N pressure, leaving gaps between waterplate and thermal pad, if we applied bigger pressure, we’ll destroy the waterplate. We adjust the compression ratio to 60%, this is all what domestic counterparts can do. But customer said we need to improve 10% more after assembling. The other two suppliers said it can not be done, this is the most we can do. But GLPOLY is still working on it, changing raw materials, adjusting additives. Finally, we achieved a conpression ratio of 72%. GLPOLY imported raw materials from Germany and Japan, and processed raw materials again with nanometer grinder, making particle size samller to improve heat transfer. Now GLPOLY is a quality partner to NIO, GAC etc. auto enterprises. GLPOLY help keep your devices performing at their best.
