WEINHEIM, Germany—Freudenberg Sealing Technologies has developed a "union of opposites" with its new thermal interface material for the electric vehicle industry.
The heat-conductive and electrically-insulating silicone material already has garnered interest from several OEMs for its wide-ranging applications.
"The new (thermal insulating material) ... combines seemingly incompatible properties by being both thermally conductive and electrically insulating at the same time," Freudenberg said in a June 27 release.
The TIM adheres to many of the substrates found in EVs, including plastics, aluminum and copper.
And the material can be applied to rough areas, filling in gaps and smoothing the surface of the substrate.
"This project was right up our alley, because our material is predestined for a wide range of complex electrical applications," said Armin Striefler, product and process developer at FST. "With its numerous qualities, it provides the right answers."
The new material was developed with versatility in mind, even for projects that feature great complexity.
"An important advantage for efficient series processes is that this elastomer material can be processed through injection molding," Striefler said. "This makes its use very flexible, since nearly all three-dimensional geometries are possible and, thanks to its material properties, it always adheres optimally to the substrate, whether plastic or metal."
The material can be sprayed on, Streifler said, and it does not require a primer.
