Electrical adhesive tapes for electrical insulation

Electrical adhesive tapes are used in electric motors, transformers and generators for electrical insulation and mechanical protection.

Our adhesive tapes are also ideal for mechanical protection and are used for labelling, bundling or marking. To meet your exact requirements, we offer a range of different material and adhesive combinations for electrical adhesive tapes.

Since electrical tapes are often exposed to high loads, we manufacture them according to the strictest standards and test them for reliability. This is how we ensure the quality of our adhesive tapes - in addition, we carry out further material tests in our SynLab^® in-house laboratory on request.

Adhesive tapes always consist of several layers. The base material, also called backing or carrier, is usually a flexible insulating material and forms the basis for the actual electrical adhesive tape.

There is a release coating on the outside of the backing which is adhesive-repellent, preventing the tape from sticking to itself and making it easier to unwind.

The inside of the backing material is coated with a bonding agent that ensures a permanent bond between backing and adhesive. Finally, the actual adhesive is applied on top this bonding agent.

Depending on your application, you may need a different structure for your electrical adhesive tape. For this purpose, we offer a wide range of different base materials and adhesive types. The properties of the different base materials in combination with the appropriate adhesive result in a completely new, highly technical product that can be used in a wide variety of applications in the electrical industry.

Polyimide adhesive tapes are particularly suitable to ensure first-class heat resistance and dielectric strength.

Polyester film adhesive tapes are highly flexible insulating tapes that have high dielectric strength even when the material is thin.

Extremely flexible and at the same time highly tear-resistant are the electrical adhesive tapes made of glass fibre. In addition, they offer high temperature resistance and are available with rubber, acrylate or silicone adhesives.

Other base materials: films (polyester, PEN, polyimide, etc.), polyester fleece, acetate fabric, aramide paper, paper, metals and many more.

Acrylic adhesives are temperature and ageing resistant. Furthermore, they are characterized by their good resistance when used with impregnating agents.
Thermal class F: Resistant to impregnating agents

Rubber adhesives have a high initial tack and are very easy to process. However, they are not resistant to impregnating agents.
Thermal class B: Very high initial tack

Silicone adhesives are characterized by high temperature and ageing resistance. They are well suited for bonding to anti-adhesive, i.e. poorly adherent substrates and can be removed without leaving residues.
Thermal class H: High temperature and ageing resistance

Our electrical tapes are classified into specific insulating material classes. Classification is based on the determination of limit temperatures. The respective letter in the name of the tape indicates the maximum continuous temperature to which the tape can be exposed. We offer insulating tapes in the following insulating material classes:

A 105 °C
B 130 °C
F 155 °C
H 180 °C

We carry out many analyses and tests in our in-house laboratory SynLab^® to ensure the highest quality. For example, for many of our UL-certified electrical adhesive tapes.

If you need further examinations, please contact our SynLab^® experts. In addition to material analyses and service life measurements, we offer you a broad portfolio of tests and measurement methods to ensure the quality of materials. In addition, we support you in the new approval, expansion or adaptation of existing UL systems.
