Description
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-D*5H
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-D*5H
features 1) short curing time, draft in 5 minutes and become
steady in *2 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-D*5H performed normally, the
variety of parameters are less than *0%. 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.
