Are there adhesive tapes that conduct electricity?

For sure! And there are not only electrically conductive adhesive tapes that conduct and direct electricity, but also adhesive tapes that are electrically insulating. But let's take a closer look!

Are there adhesive tapes that conduct electricity?

Electrification and the strong growth of e-mobility are also changing the challenges for automotive components. Adhesive tape offers you both solutions for the controlled discharge and steering of current and for electrical insulation to protect the electrical components in the vehicle, support a long service life and, above all, create a safe usage environment for consumers:inside. 

Conduct electrically
Many electronic devices in a confined space increase the likelihood of short circuits as well as interference from electromagnetic interference. Currents must therefore be conducted in a controlled manner to avoid just that.

Electrical insulation
But where there is a lot of current flowing, there is also a need for insulation. Reliable insulation is particularly important in battery construction. Electric motors, for example, should be as small as possible, and the batteries in turn should have ever greater power and capacity. This increases the power density enormously and creates a large amount of internal energy that must be insulated to prevent sparking between the internal components.

Electrically conductive adhesive tapes

Isotropic materials

These conduct the current in three dimensions (X/Y/Z axis). They are therefore particularly suitable for EMC shielding or for fastening electrically conductive seals.

Anisotropic materials

Here, the current is only conducted along the Z-axis. In the other directions, the material has an electrically insulating effect. This is made possible by electrically conductive particles incorporated into the material. These create an electrical connection between two or more contact points.

They are used in all conceivable electronic components to protect against short circuits and interference.

Electrically insulating adhesive tapes

Dielectric materials help with electrical shielding. They form an electrically insulating barrier and thus prevent components from being damaged by spark voltage. At the same time, they extend the service life.

They are therefore mostly used to insulate electronic components and especially in battery construction. Here, on the one hand, the material can provide for the fixation and connection of battery cells, modules or cooling plates, and on the other hand, electrical insulation tapes help to insulate the battery and thus prevent overvoltage.
