Kapton heater

Polyimide/Kapton Heater

Polyimide(Kapton® is a DuPont Trademark for Polyimide) is a thin, lightweight polymer film which provides excellent tensile strength, tear resistance and dimensional stability. This kind of material is widely used in flexible PCBs production for over 30 years and will provide low outgassing in vacuum environment and also resistance to radiation,fungus and many other substances. With the process of using photo-imaging technology, the etched foil element will have excellent circuit repeatability which lowers production cost and superior heat transfer. This results from being able to space the elements very close to each other which provides more surface area.

Polyimide Heater Benefits

  1. Excellent physical and electrical properties result in thermal stability over a wide temperature range.
  2. Suitable for vacuum environments(NASA-RP-1061) and is a NASA approved material for space applications(S-311-P-079).
  3. Resistant to most chemicals: oils, solvents, acids and bases.
  4. Formable, flexible and bondable to metalwork using a wide range of adhesive options.
  5. Base materials can be clad with a variety of foil element alloys such as inconel, nickel, copper, nickel-iron and many stainless steels.
  6. Can provide twice the watt density of wire wound heaters.
