Is Kapton an insulator?
Kapton® is not just an electrical insulator; it has many other properties. Its temperature stability, fire behavior and high resistance to chemicals, mechanical stress and radiation make it the ideal material for many industrial applications.
What is Kapton insulation?
Kapton tape has strong hydrogen bonds to the polar solvents used in when manufacturing it. These bonds are made at temperatures as high as 300°C, preparing the final product for high temperatures when applied. Like other polyimide tapes, Kapton tape is used for insulation, heat control, and chemical resistance.
Is Kapton tape a good thermal insulator?
The kapton tape offers excellent resistance to heat, and it is designed to be used on a series of electric masks. Ideal for wave solders, circuit board insulation, and powder coating on high temperatures, the tape has a high dielectric strength.
What temperature does Kapton tape melt?

How is Kapton made?
Polyimide film, the generic name of of DuPont’s tradename Kapton®, is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imine treatment at high temperature. It performs well in a wide range of temperatures as low as ‑452°F (-269°C) and as high as +500°F(+260°).
Does Kapton tape block UV?
One of the key features of Kapton tape, is that it blocks UV light. We need very precise IV blocking, and this tape gives us the ability to do just that.
What can I use instead of Kapton tape?
Polyimide Film Tape
Polyimide Film Tape (7000X) is a electrical grade Kapton™ alternative Polymide film coated with a high performance silicone adhesive.
Is Kapton tape double sided?
Double Sided Kapton® Polyimide Tape This double sided Kapton® tape consists of a thin Kapton® film with a silicone adhesive on both sides of the Kapton® polyimide film. This product is designed to bond on silicon substrates and can be used in harsh environments with temperatures up to 260°C / 500°F.
Who makes Kapton?
DuPont
Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable (in isolation) across a wide range of temperatures, from 4 to 673 K (−269 to +400 °C).
Who invented Kapton?
Kapton® is a unique polyimide film that was invented and trademarked by DuPont in the 1960s. Over the years, it has proven its viability as the best flexible material of choice in applications involving extreme temperature variations.
What is the thermal conductivity of Kapton sheets?
The thermal conductivity of Kapton at temperatures from 0.5 to 5 kelvin is rather high for such low temperatures, κ = 4.638×10 −3 T0.5678 W·m −1 ·K −1. This, together with its good dielectric qualities and its availability as thin sheets have made it a favorite material in cryogenics, as it provides electrical insulation at low thermal…
What are the uses of Kapton polyimide film?
Kapton polyimide film is used in a wide variety of applications such as substrates for flexible printed circuits, transformer and capacitor insulation, sensors and bar code labels. Kapton is also used for wire and cable tapes, formed coil insulation, motor slot liners, magnet wire insulation, and pressure-sensitive tapes.
Why is Kapton used as an insulator in cryogenics?
This, together with its good dielectric qualities and its availability as thin sheets have made it a favorite material in cryogenics, as it provides electrical insulation at low thermal gradients. Kapton is regularly used as an insulator in ultra-high vacuum environments due to its low outgassing rate.
What kind of temperature does Kapton stay stable?
Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable (in isolation) across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K).
