Kapton(R) polyimide film is an extremely strong, spiral wound transparent amber film that retains its high dielectric strength over a very wide range of temperatures. It remains flexible at liquid helium temperature minus 269 Degrees C and does not lose its strength until it reaches a temperature of 815 Degrees C. The maximum tubing temperature indicated in the properties chart is lower since the sealing agent used in the spiral winding process to produce Kapton(R) tubing limits its high temperature usage. Tubing made of Kapton(R) offers a rare combination of a high dielectric strength within an extreme temperature range. Kapton(R) is flame resistant and begins to char only above 800 Degrees 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(R). Due to the spiral winding process this tubing is not recommended for pressure applications however liquids and gasses may be conveyed in it. It is classified in the Superpolymer category of plastics and the benchmark for electrical and thermal insulation.
