Adhesive tapes for thermal class H
up to 180°C continuous operating temperature
For applications where exceptionally high heat is applied to the tape, CMC has developed several highly heat-resistant tapes.
Driven by a wide variety of customer requirements, a new heat-resistant adhesive tape was developed again and again from temperature-resistant base materials.
Of course, glass fabrics are ideally suited to be the basis for a heat-resistant adhesive tape. But high-performance films made of PEI (Ultem®) or PI (Kapton®) are also ideal carriers for heat-resistant adhesive tapes.
Of course, an adhesive tape also needs the appropriate adhesive. For continuous temperatures up to 180°C, CMC Klebetechnik uses very high-performance acrylate adhesives. However, if even higher temperature resistance is required, there is no getting around a highly heat-resistant adhesive.
Thus, all highly heat-resistant adhesive tapes from CMC carry a polysiloxane adhesive. Only with this type of adhesive do you get a truly heat-resistant adhesive tape that can even withstand temperatures of up to 350°C.
Such special adhesive tapes are used in high-performance engines, where sufficient reserve must be available even in the event of a malfunction. Or in stoving processes in the paint industry, for example, when parts of a housing must not be painted. In such cases, these heat-resistant adhesive tapes can even be removed again without leaving any residue. Heating elements are also often insulated with heat-resistant adhesive tape to ensure the longest possible service life of the adhesive bond.
When it comes to extreme conditions, heat-resistant adhesive tapes from CMC Klebetechnik are ideal.
A thermal class H adhesive tape must withstand particularly high thermal loads. For this reason, we only use first-class original products from renowned manufacturers of Kapton®, Nomex® and glass fabric for this class. For requirements that require, for example, a higher corona resistance (creep-stome resistance), we also offer various fluoropolymer adhesive tapes (FEP, PTFE) on request.

Information on the breakdown voltage is always given at an operating frequency of 50/60 Hz. At higher frequencies, the dielectric strength is reduced depending on the material.
Kapton® is a product of DuPont and has been distinguished by its consistent, outstanding quality for over 40 years. The polyimide films meet all requirements of UL 746, UL 94 and UL 510. Kapton can be used continuously up to 350°C and has the best chemical and physical resistance. Together with the acrylate adhesive, Kapton can be permanently fixed as e.g. insulation film on a wide variety of surfaces. Together with the polysiloxane adhesive, Kapton adhesive tapes can also be used in a removable manner (e.g. as a protective film in high-temperature applications) to the Kapton adhesive tapes
Nomex® is also a DuPont product and combines good with high resistance to moisture, chemicals and temperature. to the Nomex adhesive tapes
