Wevo’s WEVOSIL Third-Gen Silicones For EV Power Electronics

German adhesives and sealants manufacturer WEVO-CHEMIE offers thermally conductive silicone potting compounds (materials used to encapsulate and protect electronic components), gap fillers and gels for modern automotive power electronics. These customizable WEVOSIL products built from third-generation materials enable fast cycle times that lead to efficient serial production.

Wevo WEVOSIL silicones for EV power electronics

Very high operating temperatures are not uncommon in modern OBCs. Potting compounds, gap fillers and silicone gels from Wevo help sensitive components function reliably over their entire life cycle. The materials can be tailored to specific customer and component requirement profiles on request. 

To permit fast charging, the thermal conductivity of Wevo’s two-component silicones can be adjusted over a wide range: from 1 W/mK for potting compounds (WEVOSIL 22102 FL) to highly thermally conductive gap fillers with 4 W/mK ( WEVOSIL 26040 FL). 

The specially optimized WEVOSIL products also pave the way for technological advances in DC/DC converters, which today are increasingly integrated into larger units of the electric drivetrain such as the HV battery, the main inverter or the OBC.
