Even we lay lots of energy on battery management, we still don’t have a perfect thermal management solution. Besides the reasons of battery pack structure, in my point of view, thermal interface materials has a great impact on thermal management.

The market of thermal gap filler(thermally conductive adhesive) looks very chaotic, many thermal gap filler was called thermal adhesive for structure bond, actually, they are still thermal silicone encapsulant in essence. Moreover, some engineers don’t know thermal materials very well and state requirements unclear, resulting a unsatified trial and failed impression on domestic brand. Many manufacturers only concerned to thermal conductivity and laid less attention on other parameters, such as curing time, curing status, bond strength.

GLPOLY thermal gap filler (thermally conductive adhesive) XK-D12 is  epoxy based, high performance and good electrical insulation thermal adhesive which had been improved from traditional epoxy adhesive, designed for cell to pack structure for battery pack. Mix ratio is 1:1 by volume, just a few of manufacturers can accomplish it.

GLPOLY thermally conductive adhesive (thermal gap filler) XK-D12 features 1) semi rigid after curing, protect battery modules by dampening vibration, 2) Improved bond strength greater than 8Mpa, 3) mix ratio 1:1 by volume, fit for dispensing equipment. It provides high performance and ease of use.

One of our customers tested and compared materials among five suppliers, they checked thermal conductivity, electrical insulation, curing time and bond strength and so on. Two of suppliers were eliminated because of longer curing time that it is unfavourable for process. 3M TC-2810 provides a low thermal condnuctivity of 1.0W/mK.

In the high temperature aging test, GLPOLY thermally conductive adhesive (thermal gap filler) XK-D12 performed normally, the variety of parameters are less than 10%. The competing one failed because of week bond strength, and moreover, its mix ratio is 2:1 which is unfavourable for customer’s dispense process.

Besides stable thermal performance, GLPOLY thermally conductive adhesive provides reliable physical ptoperties. 1)filling gaps under low pressure, 2) low stress, 3) strong structure bond.

GLPOLY thermal materials has been applied in military equipment because of high performance and reliable properties. Thermal gap filler is on trial in battery pack in four major enterprises.

GLPOLY thermally conductive adhesive help keep battery pack cool and well performed.
