Adhesive tapes for thermal class F - up to a continuous temperature of 155°C

The adhesive tapes in heat class F withstand temperatures of approx. -20 °C to 155 °C in continuous operation. Mainly Kapton®, Nomex®, glass fabric and Teonex® adhesive tapes are available in this heat class. Special versions are also available on request. For further information, contact our sales team.

In thermal class F, besides the classical insulation materials glass fabric, Nomex® and Kapton®, the Teonex® film is also available. 
Originally, the material was developed for high-quality Flexible Printed Circuits and is now widely used as an aroma barrier in PET plastic bottles. PEN (Polyethernaphtalate) is distinguished by a higher temperature resistance compared to polyester (155 ° C constant temperature instead of 130 ° C) in the electrical sector. 
Teonex® is also superior to the classic polyester (Mylar®, Hostaphan®) under difficult conditions (dirt, moisture), since it is more stable and diffusion-proof. Polyester adhesive tapes and Teonex adhesive tapes do not differ from the processing.

For class F insulation systems, the CMC 61xxx (CMC 61100, CMC 61200) adhesive tapes are the right solution.

CMC 77700 is an excellent insulating tape. ETFE, like all fluoropolymers, has excellent aging resistance and very good leakage current resistance. Therefore, this adhesive tape is particularly suitable for high-voltage insulation and as an insulating material in the exterior.

UL: #E93622 - UL 510 flame retardant

Data on the breakdown voltage are always applied at an operating frequency of 50/60 Hz. At higher frequencies, the voltage resistance is reduced depending on the material.
