Applications

Electrical Insulation

Used extensively as insulation for motor windings — including electric vehicle, rail, and mining traction motors — as well as transformer coils, solenoids, capacitors, and wire bundling in harsh environments.

Aerospace and Defence

The material’s lightweight nature, high-temperature stability, and low outgassing rate make it ideal for use in spacecraft instrumentation, satellite components, and the insulation of wiring in aircraft.

Heater Circuits

Used in the manufacture of cartridge heaters, anti-condensation heaters, and general industrial tube heating applications, where precise and uniform heating is required.

Medical Devices

Its biocompatibility, flexibility, and ability to withstand sterilisation processes make it suitable for use in catheters, endoscopes, diagnostic instruments, and fluid warming systems.

Semiconductor Manufacturing

The need for precise temperature control and resistance to harsh chemicals in processes such as wafer processing means Kapton tubes are regularly used in this demanding industry.

Industrial and Research

Applications include use in high-vacuum environments, X-ray equipment windows, chemical processing equipment, and general-purpose high-temperature sheathing or insulation in challenging industrial settings.
