FAQ
Potting compounds reliably protect sensitive electronic components in electric vehicles against moisture, dust, chemicals, vibration, and extreme temperatures. At the same time, they improve electrical safety and extend the service life of batteries, control units, sensors, and power electronics.
Polyurethane-, epoxy-, and silicone-based potting compounds are the primary materials used in e‑mobility applications. Each material offers specific advantages in terms of thermal conductivity, flexibility, mechanical strength, and temperature resistance, and can be tailored to the requirements of the respective application.
Potting compounds are used in a wide range of electric vehicle components, including battery modules, power electronics, DC/DC converters, sensors, connectors, charging interfaces, control units, and relays. They protect sensitive components against environmental influences and ensure reliable long-term performance under demanding operating conditions.
Modern potting compounds must provide high electrical insulation, efficient heat dissipation, chemical resistance, and durability under temperature cycling and vibration. In addition, efficient processing and compatibility with automated manufacturing processes are essential requirements for the series production of e‑mobility components.
Thermally conductive potting compounds enable efficient thermal management by dissipating heat evenly throughout the battery system. This helps reduce hot spots, improves battery performance, and extends the service life of installed components. These benefits are particularly important in high-voltage batteries and power electronics.
