ATH Functional Fillers for Thermally Conductive Adhesive Applications

Special Guest Speaker(s): Pierre-Guillaume Colmard (Application Engineer at Alteo) and Pankaj Yadav (Commerical Engineer at Metravib).

Electric vehicles, and more specifically their battery chemistry and design, are constantly evolving to meet automotive market requirements such as material availability, vehicle range, public safety, and cost competitiveness. Thermally conductive adhesives and potting compounds play a critical role in managing heat in EV battery packs and power electronics, and functional fillers like aluminium hydroxide (ATH) are key to balancing thermal performance, processability, and mechanical properties.

In this webinar, we will examine how Alteo’s aluminium hydroxide ATH filler blend TIMal M3 enhances the performance of thermally conductive adhesive and epoxy based thermal interface material systems. Using C Therm’s Trident Thermal Conductivity Instrument, we will review measured thermal conductivity in representative epoxy formulations, and show how filler treatment and loading impact heat dissipation. Complementary thermo mechanical data from Metravib Dynamic Mechanical Analysis equipment will highlight changes in modulus, damping, and overall durability, demonstrating how treated fillers can be used to optimize both thermal and mechanical performance in EV related adhesive applications.
