Why thermal conductivity is not the key parameter to focus on

When it comes to potting for e-mobility components such as electricmotors, capacitors, transformers etc., there is often a trade-off between high thermal conductivity and viscosity.

High thermal conductivity is of course desirable in potting materials because it allows for efficient transfer of heat generated, for example by the motor, which can improve its performance and prolong its lifespan.

However, high thermal conductivity materials may also have high viscosity, which makes it more difficult to apply and spread the material everywhere is needed. This can lead to poor coverage and voids in the potting material, which can result in inadequate protection for the motor components and reduced heat dissipation.

On the other hand, low viscosity potting materials are easier to apply and spread evenly around the emobility components but may have lower thermal conductivity and may not provide adequate heat transfer.

In order to find the best balance between high thermal conductivity and low viscosity, it may be necessary to experiment with different materials and potting techniques. In some cases, it may be possible to find a material with a moderate thermal conductivity and viscosity that provides adequate heat transfer and protection for the emobility components.

Demak Group, thanks to its chemical and mechanical know-how, can guide you towards a solution that balances the needs of efficient heat transfer and ease of application, ensuring the best protection for your emobility components.
