Battery range is the biggest factor that restricts development of EVs, the EVs business is booming while the battery technology do not make any breakthtough. Increasing battery energy density of unit volume is the most feasible solution presently. GLPOLY XK-D series of thermally conductive structural adhesives are designed “cell to pack” (refer to“CTP”) battery pack with 8MPa bonding strength, eliminating mechanical fastening, simplifying assembly structural, increasing energy density of unit volume thus increasing range. These materials are designed to replace existing polyurethane or epoxy based thermally condutive adhesives. How are we so confident that GLPOLY XK-D products can substitute for polyurethane or epoxy products?

One customer consulted us about a thermally conductive structural adhesive with 1.2W/mK thermal conductivity and high bonding strength applying to LCTP (large cell to pack) battery. He said he had tested polyurethane thermally conductive adhesive, and he found the performance attenuated seriously in high temperature ageing test. That’s true. We had validated that the performance of PU thermally conductive structural adhesive attenuated by 40% after ageing test for 500hours, according to simulation calculation, car recall event would take place probably. That was why we abandoned PU adhesives and select modified epoxy technology. We wished to provide support to customer verifying the reliability of modified epoxy thermally conductive structural adhesives and PU. In the next year, we supplied 10kg XK-D12L product each month to this customer for testing. finally, GLPOLY thermally conductive structural adhesive emerged at the most reliable one in high temperature ageing test.

Now the trial production verification is moving forward, we are confident that GLPOLY thermally conductive structural adhesive XK-D12L would be the precise solution.

GLPOLY has been supplying thermal interface materials to leading enterprises in each industry such as LG, DJI, DT Mobile, Quectel Wireless, GAC Motor, Lixiang Motor, NIO Motor and more, helping them design tomorrow’s breakthroughs.
