FAQ
Electrical potting compounds are specially formulated materials used to protect electrical and electronic components from external influences. They permanently encapsulate sensitive components, increasing their resistance to moisture, dust, chemicals, vibration, and temperature fluctuations.
Electrical potting compounds increase the reliability and service life of electronic components. They protect sensitive assemblies against environmental influences and mechanical stress while helping reduce failures and maintenance requirements.
Electrical potting compounds are used across a wide range of industries, including power electronics, sensor technology, control units, industrial automation, energy technology, charging infrastructure, and e-mobility applications.
Depending on the application, potting compounds for electronics must meet demanding thermal, mechanical, and electrical requirements. These may include resistance to temperature cycling, flame retardancy, thermal conductivity, and resistance to moisture and chemicals.
Polyurethane, epoxy, and silicone resins are commonly used for electrical potting compounds. The choice of material depends on the specific requirements for flexibility, thermal conductivity, flame retardancy, and long-term durability.
The potting material completely encapsulates the electronic components and forms a permanent protective barrier. This prevents moisture ingress and reduces the risk of corrosion and electrical failures.
