Product information "TG Kapton Insulation Sheet"

Kapton Insulation Sheet is a polyamide film that can be used at high temperatures up to 280 degrees Celsius and acts as an assembly aid for electrically conductive thermal interface material (TIM). It is ideal for covering components such as SMDs on a CPU or GPU if they are to be used with Conductonaut liquid metal, Carbonaut or KryoSheet. 

Kapton Insulation Sheet is supplied packaged in 10 sheets of 5 Kapton adhesive strips each. Each individual adhesive strip is 10 mm wide and 60 mm long, with a thickness of 40 µm. It is recommended to thoroughly clean the contact surface to which the Insulation Sheet is applied (e.g. isopropanol).

Note on use with High Performance Heatspreaders and Direct-Die coolers

The TG Kapton Insulation Sheet should not be used in combination with High Performance Heatspreaders or Direct-Die coolers. Instead, a thin layer of TG Shield should be applied to protect the electronic components. The reason for this is that High Performance Heatspreaders (HPHS) and Direct-Die coolers rest directly on the CPU package. When a Kapton Insulation Sheet is used, the internal structure of the HPHS or Direct-Die cooler may rest on the Insulation Sheet, preventing contact between the CPU die and the HPHS or cooler.

TG Kapton Insulation Sheet

Cut TG Kapton Insulation Sheet to size with clean, sharp scissors or a blade on a suitable surface, never directly on the circuit board or CPU substrate. Apply the film to clean, dry surfaces that need electrical insulation. The actual heat transfer surface must remain clear. Avoid torn edges, wrinkles and overlapping layers under the cooler. In direct-die installations, even a thin additional layer can change the contact height. Use the protection method specified in the cooler's instructions for these installations.
TG Kapton Insulation Sheet is used to electrically insulate suitable contact areas. Its protective effect requires a clean surface. The film must not get between the cooler and the contact surface, as this would impair heat transfer. For applications with specific voltage requirements, thickness and electrical specifications must be checked separately.
Both versions are suitable for continuous temperature exposure up to 180 °C. The standard TG Kapton Insulation Sheet withstands temperatures up to 280 °C for short periods. The transparent, yellowish film allows the covered components to remain visible. TG Kapton Insulation Sheet Black Edition withstands temperatures up to 260 °C for short periods. Its matte black surface is suitable when components should also be visually concealed or when the yellowish film does not suit the design.
