Key factors to consider about insulation materials

Thermal and electrical insulation materials such as fish paper, Formex, polyimide (Kapton) and Mylar are all great options when needing a material with high dielectric strength that can be easily die cut. However, not all insulation materials are created equal, so it can be overwhelming to determine which one you need.

When determining which electrical insulator material to use, you need to consider:

  • Dielectric strength
  • Cost
  • Desired thickness

These materials are rated in the form of volts per mil. So once you know the level of insulation you need, you can easily convert this to determine your minimum material thickness.

But that's not all there is to it.

What is the application?

When choosing which type of electrical insulator material to use, you also need to look at the application itself. If the insulator will be used in a flat form, you might choose one material. But if it will be required to bend, wrap around an object or retain a scored and formed shape, you might want to choose something totally different.
