Adhesive tapes for thermal class F
up to 155°C continuous operating temperature
The adhesive tapes of thermal class F withstand temperatures from approx. -20°C to 155°C in continuous operation. Kapton®, Nomex®, glass fabric and Teonex® adhesive tapes in particular are available in this thermal class. Special versions are also available upon request. For further information contact our sales team.
In thermal class F, Teonex® film is now found alongside the classic insulation materials glass fabric, Nomex® and Kapton®. Originally developed for higher-quality flexible printed circuits, the material is now frequently used as an aroma barrier in PET plastic bottles. PEN (polyether naphthalate) is particularly suitable for the electrical industry due to its higher temperature resistance compared to polyester (155°C continuous temperature instead of 130°C). Teonex® is also superior to classic polyester (Mylar®, Hostaphan®) in aging tests under difficult conditions (dirt, moisture) because it is more hydrolysis-resistant and diffusion-proof. In terms of processing, polyester adhesive tapes and Teonex adhesive tapes do not differ.
For class F insulation systems, the CMC 61xxx series of tapes (CMC 61100, CMC 61200) are the appropriate solution.

approx. 500 Vrms. |
Strip coated polyester nonwoven with good impregnation properties, can be used for this thermal class using an impregnating agent of thermal class F. Popular tape for wrapping head bandages, phase separation and coil termination. |
|
| CMC 80736 Polyester fleece colour: white strip coated Total thickness: 0.140 mm |
- |
Strip-coated polyester nonwoven with good impregnation properties, can be used for this thermal class using an impregnating agent of thermal class F. Adhesive tape for wrapping head bandages, phase separation and coil termination. |
|
|
CMC 84160 Glass fabric Colour: white Adhesive: rubber Film thickness: 0.120 mm Total thickness: 0.180 mm |
2.000 Vrms. |
ATTENTION: according to UL only class B (test method dependent). Due to the rubber adhesive, high initial adhesive force of the glass fabric adhesive tape. Use e.g. for pole shoe, frequency converter (drive controller), line filter, current transformer, azimuth motor, high voltage mains transformer, variable transformers, autotransformer, generally as coil head tape. |
|
|
CMC 84170 Glass fabric Colour: white Adhesive: Acrlyate UL 510 Film thickness: 0.120 mm Total thickness: 0.165 mm |
2.000 Vrms. |
Due to the acrylate adhesive better impregnant resistance of the glass fabric adhesive tape. Use e.g. for pole shoe, frequency converter (drive controller), mains filter, high voltage mains transformer, variable transformers, autotransformer, generally as coil head tape. Very temperature resistant adhesive tape |
|
| CMC 86719 Laminate polyester film/glass filaments Colour: colourless Adhesive: acrylate |
5.000 |
Highly tear-resistant adhesive tape due to glass filaments, resistant to transformer oil, used in transformer and motor construction |
|
|
CMC 77700 ETFE adhesive tape Colour: colourless Adhesive: polysiloxane Film thickness: 0.100 mm Total thickness: 0.160 mm |
3.000 |
CMC 77700 is an excellent insulating adhesive tape. ETFE, like all fluoropolymers, has outstandingly good aging resistance and very good tracking resistance. Therefore, this tape is particularly suitable for high-voltage insulation and as an insulating material in outdoor applications. |
