Product Description

Current Stock is: 1 Mil Kapton Tape (Polyimide) - 1/2" X 36 Yds (0.50 inches wide by 108 feet, or 12.7mm wide by 32.9184 Meters)

Developed by DuPont and favored by NASA since the days of Apollo, this polyimide film is exceptional for its high thermal resistance, high dielectric strength, high X-ray transmittivity, and its mechanical stability at temperatures ranging from absolute zero to 200°C.

Employ this tape as a substrate for 3D extrusion printing; as a mask for hot-air soldering; as the dielectric in a high-voltage capacitor, as an electrical barrier between closely-stacked circuit boards; or as insulation for hot wire.

It is coated on one side with zero-residue high-temperature silicone adhesive.


1Mil Kapton tape is developed by Dupont which is a HN general purpose film with silicon adhesive. Kapton® polyimide films shows excellent electrical insulation properties, high temperature resistant, and excellent solvent resistant. Kapton tape combines excellent physical, electrical, and mechanical properties, and has been used in applications at temperatures as low as -273°C (-459°F) and as high as 400°C (752°F).
