The rapid advancement of the electric vehicle (EV) market is no secret, and to keep pace with this progress, OEMs seek cutting-edge thermal management solutions that perform well and come at a reasonable cost.

Among essential materials used for heat management in EV batteries, thermal gap fillers play a crucial role. Marian collaborates with suppliers like Polymer Science, whose partnership allows for development of high-quality gap filler materials along with various other essential materials for managing heat in electric vehicles.

We sat down with John Biddle, Vice President of Product Development at Polymer Science for a Q&A session where we delved into their contributions to the production of thermal management material and the benefits they bring to the EV world.

Thermal gap pads are utilized in electronic devices within the interface, or gap, between a heat generating component and a heat sink. The heat sink or cooling plate is designed to conduct heat away from the heat generating component to keep it cool and running safely. According to Parker Chomerics Thermal Management Engineering Handbook, the typical contact area between most semiconductors and heat sinks can be made up of 90% air voids! We also know that air is about 200 times less conductive than a 5 W/mK  thermal interface pad. This is where the thermal gap pad comes in.

Thermal gap pads are made of soft polymer that flows into the air gaps in the interface to aid in the more efficient and effective conduction of heat.
