Although technologies over electrical vehicle has been developed for years, we still dont have a perfect thermal management solution over electrical vehicle battery pack. Besides the reasons of battery pack structure, I think 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 dont 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, maintaince.
GLPOLY thermal gap filler (thermally conductive adhesive) XK-D25H is epoxy based, high performance and good electrical insulation thermal adhesive which had been improved from traditional epoxy adhesive. Mix ratio is 1:1 by volume, just a few of manufacturers can accomplish it, for example, 3M thermally conductive epoxy adhesive mix ratio is 2:1. It is truth that data can be checked out from website.
GLPOLY thermally conductive adhesive (thermal gap filler) XK-D25H features 1) short curing time, draft in 5 minutes and become steady in 12 hours, 2) semi rigid after curing, protect battery modules by dampening vibration, 3) Improved bond strength greater than 3.7Mpa, 4) mix ratio 1:1 by volume, fit for dispensing equipment.
One of battery 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.
In the high temperature aging test, GLPOLY thermally conductive adhesive (thermal gap filler) XK-D25H 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 customers robot system.
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 thermal materials help you keep you devices cool and well performed.

Applying Process 1.Surface clean : Clean the surface of the adhesive object and remove the rust, dust and oil. 2.Sizing: Twist the cap of the hose, squeeze the gel into the clean surface, and make it natural. 3.Curing: Place the bonded or sealed parts in the air while them to solidify naturally. Curing is a process from surface to the internal, within 24 hours (at room temperature and 55% relative humidity) will cure the depth of the 2 ~ 4 mm, if the site location is deeper that completely curing time will be postpone, especially it is not easy to come into contact with air. if the temperature is low, cure time also will be postpone .Prior to further processing or wrapping the bonded parts, it is recommended that the user wait long enough to ensure that the adhesion and integrity of the adhesion are not affected.
