Kapton® HN

Kapton® HN general-purpose polyimide film

Kapton® HN is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.

Kapton® HN has been used successfully in applications at temperatures as low as -269°C (-452°F) and as high as 400°C (752°F). Kapton® HN film can be laminated, metallized, punched, formed or adhesive coated.

Applications include:

  • Mechanical parts
  • Electronic parts
  • Electrical Insulation
  • Pressure sensitive tape
  • Fiber optics cable
  • Insulation blankets
  • Insulation tubing
  • Automotive diaphragms sensors and manifolds
  • Etching
  • Shims
