Take CGW-2 as benchmark model, GLPOLY launches an alternative product—thermal gap filler XK-S20. More than 20 technical data had been tested, GLPOLY is the only one that possess such a professional inspection ability. We don’t just give customer a specification, we’ll test physical, electrical and thermal properties according to customers’ statement after we get samples, then we test every parameter of GLPOLY thermal gap filler XK-S20, all these test reports will be submitted to customers. Actually, many counterparts don’t even undertand the test standard of each parameter. How they can provide alternatives. Firstly, silicone oil leakage is less than 5% by test standard of ASTM D120. Maybe some people laugh at us why do you release the true report? Customers don’t know the detail. We don’t provide fake data and never. Test report showed that XK-S20’s oil leakage is half of CGW-2’s. Secondly, Pressure and compression. 30% of compression under 40psi, it’s tested by universal mechanical instrument. During the test, GLPOLY R&D supervisor found that this test standard is not fit for compression test. GLPOLY drew up a scheme for compression test, it is not only considered as corporate standard, but also industry standard. Thirdly, viscosity. This is one of most concerned points. Viscosity affects quality and dispensing speed of thermal gap filler. Once, one of our customers said GLPOLY XK-S20’s viscosity of 320pas is too high, and requested us to decrease the value to 240 pas which CGW-2 provides. Actually CGW-2 provides a viscosity of 330 pas, “maybe there is difference between test instrument or given revolution .” We discussed this with customer. When we contrast the data, we need to understand or make clear if there is any difference between customer’s test standard or instrument and ours. To be honest, GLPOLY is the only one that provides true comparison between its products and competitors’.

How should we select Al or Al-plastic film in “cell to pack” structure of blade-like battery and “811”battery? GLPOLY thermally conductive structrual adhesive is overturning the market. With the boom of “cell to pack” structure of battery pack, a dramatic increase in energy density raised. But battery pack thermal management is lagging behind. In such a situation, GLPOLY has launched XK-D series of thermally conductive structural adhesive to solve thermally conductive and bonding strength problems of “cell to pack” battery pack. Here is the analysis for your reference. 1) According to our DFEAM , when the Al-plastic film used, we found that the bonding strength of Al-plastic film is less than 1.0MPa, “Al-plastic film” structural battery pack will be destroyed, even cause explosion easily in disaster impact. Al-Al is the best for reliability, security and enviromental adaptability, even the cost. 2) At present, there is a dozen varieties of three kind of categories, including”Al-Epoxy film”, “Al-PVC film” and “Al-Acrylic film” at least, even more fake products. 3) Cost: “Al-Al” structure is the most economical way at present. 4) More seriously, many engineers deemed that thermally conductive epoxy adhesive is brittle and raised resistance to our XK-D series of thermally conductive epoxy adhesive. Actually, our XK-D products provide a better elasticity than nylon. 5) Some engineers prefered Polyurethane based thermally conductive adhesive to Epoxy based thermally conductive structural adhesive. If the “Al-Plastic film” was not abandoned, the polyurethane could not bring you any benefits too. This will offer market space to fake products. GLPOLY two-component thermally conductive structural adhesive has been applied to celle to pack battery pack in several car makers and battery pack manufacturers. GLPOLY has partnered with dJI, Huawei Marine, DT Mobile, Han’s Laser etc top-class brands, providing high performance thermal interface materials for them to protect their brand reputation for performance and reliability.

He had a tough thermal management problem suspended due to previous samples’ failure to meet requirements. I sent him the specification of thermally conductive epoxy adhesive XK-D12H for evaluation. Two days later, he called me that his team had assessed the data sheet and found specification satisfied, so he wanted to apply for samples for testing at their facility. I said all samples were charged, but the cost could be shared in bulk production in the future. Customer accepted and bought five samples in 400ml cartridge each. Customer told me samples would be verified for six months for high temperature aging test and high and low temperature thermal shock, it really was unexpected because most the customers would verified samples for two months. Though we would spend more time, I appreciated customer’s rigorous and serious attitude. Then customer seemed to disappear in the next six months. I almost forgot this project. One day, I received a call from this customer, he said XK-D12H performed excellent no matter thermal performance, bonding strength or hardness, comparable with TC2202. In this case, customer decided to purchase XK-D12H instead of TC2202 due to lower cost and 7-day lead time. Now trial production was in progress and a bulk production schedule was proceeded.
