Why must thermally conductive structural adhesive be used in CTP structure? Not only for better heat transfer, but for eliminating module structure to increase energy density and battery life.

GLPOLY thermally conductive structural adhesive is in trial production in F company and A company, both thermal conductivity and bonding strength are the most excellent in domestic industry.

As the boom of concept of CTP structure, internal strucutre of power battery pack is undergoing great change, non-modularization is being designed and applied gradually, and it’s firstly applied by CATL company. Then some automakers and battery manufacturers were following suit. What’s the difference between CTP battery pack and traditional module battery pack? Obviously, there is no extra housings, all the cells are bonded by structural adhesive. Functions of gap filling and heat transfer will be performed by thermally conductive adhesive. GLPOLY thermally conductive structural adhesive is such a gap filling material that designs to improve CTP battery pack thermal management.

What are advantages of GLPOLY thermally conductive structural adhesives? Firstly, it has strong bonding strength which is greater than 8MPa, eliminating the need of mechanical fasten, keeping the battery cell bonding firmly in operation, increasing energy density and battery life.

Thermal conductivity of GLPOLY thermally conductive structural adhesive is optional from 0.8 to 13W/mK, improving not only the bonding issue, but also heat transfer.

Production processes comply with IATF16949, keeping consistency of products. GLPOLY is the first one that introduce automated production processes to eliminate human error, and let customer rest assured.

GLPOLY thermally conductive structural adhesive has been applied to EV battery pack in volume production with high performance and reliability. If you have any queries, please feel free to contact GLPOLY.
