German adhesives and sealants producer Wevo-Chemie has introduced a new line of WEVOSIL thermally conductive silicone potting compounds, gap fillers, and gels designed for DC/DC converters, which are becoming increasingly integrated into larger units of electric drivetrains such as the HV battery, main inverter, and OBC. These two-component silicone products are made from third-generation materials, allowing for fast cycle times in efficient serial production. They can be customized in terms of flow behavior, pot life, hardness, and basic adhesion, enabling sensitive components to function reliably at high operating temperatures commonly found in OBCs.
The products from Wevo-Chemie are specifically formulated to help components maintain functionality throughout their entire life cycles under high temperatures. To support fast charging, the thermal conductivity of the silicone products can be adjusted across a wide range, from 1 W/m·K for potting compounds to up to 4 W/m·K for highly thermally conductive gap fillers. The silicone gels in the line are designed with pronounced tackiness, allowing them to adhere to the housing even when fully cured, despite the high operating temperatures experienced during use. This combination of properties makes the WEVOSIL silicone products ideal for applications in DC/DC converters and other electric drivetrain components.
In addition to thermally conductive silicone products, Wevo-Chemie also offers a portfolio of polyurethanes and epoxy resins that can be customized to specific component and customer requirements upon request. This flexibility in customization allows Wevo’s developers to tailor their products to meet the specific needs of individual applications, ensuring optimal performance and durability in various settings.
