Kapton®

General Description:
Kapton® polyimide film is an extremely strong, transparent (amber) film that retains its high dielectric strength over a very wide range of temperatures. It remains flexible at liquid helium tem­perature (-269°C) and does not lose its strength until it reaches a temperature of +815°C. The tubing properties shown below are in a lower range as the sealing agent used to produce Kapton® tubing limits its high temperature usage.

Advantages: Tubing made of Kapton® offer a rare combination of a high dielectric strength within an extreme temperature range. Kapton® is flame resistant and begins to char only above 8OO°C. It does not melt and is self-extinguishing. It has excellent mechanical properties and is practically unaffected by moisture. There is no known organic solvent for Kapton®.

Minimum Wall Thickness: .003" to .010" Tubing ID: .090" to 01.5"

Suggested Uses: Coil forms, capacitor and resistor covers, spacers, bobbins, slip-on wire insulation.
