Pressure-sensitive adhesive films are increasingly important in electric vehicle battery modules, where they help bond pouch cells, support module assembly, and influence how heat moves through the battery pack. For EV applications, knowing whether an adhesive acts as a thermal conductor or a thermal barrier is critical for battery safety, cell longevity, thermal runaway management, and overall pack performance.
This webinar explains how to measure the thermal conductivity of thin pressure-sensitive adhesive films using C-Therm’s Trident Thermal Conductivity Instrument with the TPS Thin Films Utility. The method allows direct measurement of micron-scale adhesive films in accordance with ISO 22007-2, without requiring multiple layers to be stacked into a thicker sample. This is important because stacking thin films can introduce interfacial defects and skew the measured thermal conductivity.
Using Adhesives Research Inc.’s EL-94865 acrylic pressure-sensitive adhesive film as an example, the session will show how thermal conductivity testing can be used to evaluate film thickness, production consistency, adhesive layering, and the effect of a PET-laminated interlayer. The results demonstrate how the TPS Thin Films Utility can measure the intrinsic thermal properties of thin adhesive films and help R&D teams determine whether a material has been produced in an optimal state.
Attendees will learn how thin-film thermal conductivity data supports EV battery material selection, adhesive formulation, thermal barrier design, process optimization, and battery module thermal management.
