General DescriptionKapton ® 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.
|Material Properties* :|
|Temperature Range - °C:||-269 to +400|
|Dielectric Strength - VPM (@ 25"C.):||7,000|
|Volume Resistivity - ohm/em (@ 200°C.):||1.0x1016|
|Moisture Absorption (@ 23.5°C.,50% RH):||1.3%|

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.
