How do test methods affect silicone thermal conductivity results?

Heat dissipation is critical for the electronics and batteries to function for their intended lifetime and reach the desired levels of performance and reliability in EV applications. Without proper thermal management, lithium-ion batteries can overheat during charging or discharging. There can also be a non-uniform temperature distribution within the battery packs which may affect optimal performance, ranging between 15 °C and 35 °C.

Knowing the thermal conductivity of both thermal interface materials and thermal insulating materials is key to being able to determine how well these materials will perform in an application. Having consistent conductivity test methods that correlate to the end application is an absolute critical aspect of the material selection process.

Elkem Silicones – a fully-integrated global raw material silicone supplier – has analyzed four different test equipment and test method standards at global laboratories to help determine which best aligns with customer’s applications.
