Efficient thermal management is critical for reliability and performance of high power electronics, especially those found in automotive applications. With the protection of sensitive electronics from overheating in mind, Toyochem researchers in Japan were able to solve the performance trade-off problem between the elastic modulus and thermal resistance that typically arises in conventional epoxy-based thermal interface materials.
The LIOELM FTS is a thermal material that maintains an ultra-low elastic modulus. Due to its soft consistency and special rheology, the LIOELM FTS fills in every void and conforms to every rough surface. Along with an ultra-low modulus, the LIOELM FTS demonstrates excellent thermal durability and insulation reliability at high temperatures (up to 180°C), while still maintaining good thermal conductivity (up to 10W/m-K), the company reports.
Toyochem researchers accomplished this by combining its unique polymer with highly conductive fillers to create a thermal interface with excellent bond strength and high conductivity, and durable dielectric strength.
Toyochem will be spotlighting the LIOELM FTS thermally conductive adhesive sheets and its other thermal management solutions at the PCIM (Power Conversion and Intelligent Motion) Europe 2018 in Nuremberg, Germany from June 5-7.
