Why Use GLPOLY Thermally Conductive Adhesive In EV Batteries

Product Details

GLPOLY thermally conductive structural adhesives are modified epoxy based patented new materials designed for solving thermal management challenge of “cell to pack” (refer to CTP) battery pack.

Generally, the market is flooded with two kind of thermally conductive structural adhesives, namely polyurethane and epoxy based products. Actually thecnologies of these two products are really backward and are not ideal for automotive or EV applications.

GLPOLY thermally conductive structural adhesives are new materials aimed at taking the place of PU and epoxy based thermally conductive adhesive products with high reliability. For example, after extreme temperature cycling and shock for 500 cycles, the key indexes change is less than 10% before and after test, but for PU and epoxy based thermally conductive adhesives, the performances will decrease by 40%. The comparison is not fabricated but real outcome of simulation test. Test report is available for you.

Premium thermally conductive structural adhesives combine fantastic bonding strength and unrivaled thermal management capabilities. This allows for necessary heat dissipation in battery pack, while also eliminating the need for mechanical fasteners, simplifying structure, saving space and increasing energy density of unit volume thus increasing battery range and service life.

Also this makes thermally conductive structural adhesives the perfect option when assembling smaller, lighter applications .

GLPOLY thermally conductive structural adhesives apply to EV “cell to pack” battery pack with the features and advantages:

1. Thermal conductivity 1.2W/mK-3.0W/mK; Bonding strength 8MPa at least, twice as high as competitive products’;

2. Withstanding 12m-falling impact;

3. Thixotropic viscosity for easy dispense; room temperature and elevated temperature cure;

GLPOLY thermally conductive structural adhesives are in trial in leading enterprises such as Farasis Energy, Lixiang Motor, LISHEN Battery, AIWAYS Motor and more. It’s a trend to adopt a new thermally conductive structural adhesives to battery cell bond replacing PU and epoxy based thermally conductive adhesives. Modified epoxy thermally conductive structural adhesives shall be the solution, I believe.
