In response to the needs of automobile customers, GLPOLY TIM has been using actual testing data to testify the authenticity of thermal conductive performance, that is strong evidence to convince customers adopt us.

XK-D series will be a part of the new model electric vehicle of 2020

From GLPOLY TIM new project.

Battery pack energy density 300 Wh/Kg above, if the charging and discharging efficiency (or endurance mileage) is required to reach more than 85%, the thermal conductivity should be higher than 2.0 w/m k. so that GLPOLY TIM develop a kind of new thermal conductive material : Thermal conductive structural adhesive XK-D25

Features: 1:1 two componets liquid before cured;  3.7mpa bonding strength can replace the screw fixing;  2.5w/m·k thermal conductivity satisfy the battery thermal design; Non-silicone; service life more than 10 years.

At present, This thermally conductive material is in the aging testing stage required by customers.

Meanwhile, we have read the competitor’s technical data sheet, which it made by domestic factory.  Different opinions we have: The density is 2.18 g/cm3, thermal conductivity only 1.3 w/m · k, that is too low; The viscosity is too high, 1:1 two components mixing, basicly not matching the operation of automated dispenser.

Our chief engineer believes that the research and development of new design is accompanied by actual testing. We should provide the matching thermal conductivity materials that will not cause any market quality problems. Safety and reliability are related to the shear bonding strength, numerous producing technique and processing parameters. Not all the manufacture factory will do more than 17 test items, but GLPOLY TIM did
