With proven reliability, modified epoxy thermally conductive structural adhesives surpasses PU adhesives completely.

As popularization of CTP battery pack, the demand for thermally conductive structural adhesive rises rapidly.

You may say the mainstream offerings are epoxy and PU thermally conductive structural adhesives in the market. Yes, you are right. In the past years, even they occupied great market share, engineers still remained cautious in application of epoxy and polyurethane products in automobile. Why? Reliability concerns. In the simulation test carried out by GLPOLY, we could see that the performance degraded by 40% after aging test at 125 Celsius degree for 500 hours. It’s really not a perfect thermal management solution to automotive application, especially to battery pack.

For solving the problem of reliability, GLPOLY explored new technical means. After four years of research and practice, GLPOLY launced XK-D series of thermally conductive structural adhesives with thermal conductivity 1.2W/mK-2.0W/mK. The test report showed that modified epoxy technology would be the best and most reliable.

What kind of material are XK-D series of thermally conductive structural adhesive? XK-D12, for example.

GLPOLY XK-D12 thermally condutive structural adhesive is designed to improve thermal management and battery cell bond of CTP battery pack. This material has a thermal conductivity 1.2W/mK and bonding strength 8MPa. After aging test at 125 Celsius degree for 1000 hours, the change of key data is less than 5%. We can see the hugh differences on reliability. This reported was based on measured data, not fabricated by imagination.

GLPOLY XK-D12 thermally conductive structural adhesive has the features and advantages:

1. 1.2W/mK thermal conductivity, 8MPa bonding strength;

2. Proven reliability in high and low temperature cycling and thermal shock;

3. Eliminates the need of mechanical fasten, increasing volume by 20%, reducing components by 40%, improving productivity by 50%, competitive products can’t achieve these objectives;

4. Approved by GAC and Gotion, competing against world’s class brands such as Lord, 3M etc;

5. Bonding strength is 30% higher than that of competitive products, withstanding impact of 12m freefall superimposing speed of 120km/h ;

6. Automatic production lines ensure consistency of products, that is our value and life of enterprise;

GLPOLY thermally conductive structural adhesives have been applied in CTP battery pack in AIWAYS Motor, Lixiang Motor, Gotion Battery, LISHEN Battery, Farasis Energy and more. We are confident that it’s just a matter of time before GLPOLY modified epoxy thermally conductive adhesives substitute for PU adhesives in battery pack applications.

Have a try, you are worth a better solution.
