Thermal Conductivity Performance Testing of Potting Compounds for Power Electronics

Lower operating temperature, while increasing power output and engine life

Potting compounds are widely used in electric vehicles.  Potting or encapsulation compounds can lower the operating temperature of electric motors, resulting in higher power output, longer engine life, and better reliability.  Improving thermal conductivity of these compounds is important in reducing the electric motors operating temperature and improved performance. C-Therm will be presenting a webinar focused on performance testing of potting compounds.  The session will feature thermal conductivity case studies from industry, discussing the best test methods for potting compounds and related materials using C-Therm’s Trident platform.

Electric Motor Thermal Conductivity

Electric Motor Component Thermal Conductivity is a Critical Performance Attribute

Filled polymers are often used as potting compounds in electronics, to reduce thermal contact resistance and secure electrical components. Potting compounds are designed to be solid or gelatinous materials that provide structural support and physical protection of electronic components while also displacing heat to reduce thermal load. This form of thermal management is amongst one of the many that are employed across various temperature-sensitive applications and popular in one of today’s fastest-growing research sectors – battery components for EVs.

Increasingly, there is a demand for potting compounds with improved thermal conductivity for better heat dissipation in such high-performance devices. Accurate and repeatable measurement of thermal conductivity at a wide range of temperatures is a critical performance check to ensure stable operation in both active and resting states. Additional considerations such as filler dispersion, settling and the introduction of anisotropy can also add to the complexity of obtaining valid results.

Join us for this upcoming webinar where we will discuss the best test methods for potting compounds and related materials. C-Therm’s Trident platform will be highlighted using both Modified Transient Plane Source (MTPS) and Transient Plane Source (TPS) methods. This presentation will include data collected using both methods and will include various case highlights from leading research groups across a range of applications where thermal management is crucial to overall performance.
