GLPOLY Thermally Conductive Structural Adhesives Are Designed For CTP Battery Cell Bond.
GLPOLY thermally conductive structural adhesives XK-D range of products are divided into two catetories in terms of application, XK-D12 is used for soft packing battery (pouch cell), the other sort like XK-D20 and XK-D30 are designed for prismatic battery.
Many customer asked which project is GLPOLY thermally conductive structural adhesive being applied when they contacted GLPOLY for the first time. Actually, thermally conductive adhesive was just used by C company and B company in high volume, for other companies, it’s just small-scale application. At the productronicachina exhibition, the R&D director visited our booth and chatted with our coleagues:” Wacker did not involve in thermally conductive structural adhesive, do you think it’s a trend that thermally conductive adhesive applied in new energy electric vehicle battery pack? Now we are starting to develop thermally conductive structural adhesives too.” It’s a trend or not, we don’t want to define, but we are fully confident of boom of delivery of thermally conductive structural adhesives after 2022.
I’ve sorted out the materials of new energy EV CTP battery pack and found that the items concerned most by engineers were thermally conductivity, tensile strength, shear bonding strength, hardness, elongation and shelf life etc, in addition, the fluency of dispense and fluidity of material were concerned too. The design requirements of each customer are dissimilar, but it does not matter, GLPOLY is confident of providing customized service for customers.
1. Has no equals in features of bonding strength, roughness, thermally conductive and electrical insulation;
2. Bonding strength is 30% higher than that of competitive products, withstanding impact of 12m freefall superimposing speed of 120km/h ;
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;
