Kapton®, a polyimide material that has high dielectric strength, allowing for a very thin heater construction. Chromalox uses Kapton® with two types of bonding systems; FEP Teflon® Thermo-flow polymer 392˚F (200˚C), and Acrylic Thermo-flow 250˚F (121˚C). Kapton® heaters have superior dimensional stability, light weight, and flexibility.


  • Thin, lightweight, low out gassing
  • UL: Optional
  • Bend Radius: 0.032" (0.8 mm) minimum
  • Resistance to most solvents and acids and radiation to 10^6 rads
  • Ability to place heat where it is needed, even controlled heat profiles
  • Thin construction means fast thermal transfers which equates to quick heat up
  • Very small sizes
