Kapton / Nomex Laminates: High-Temperature Electrical Insulation Solutions

Kapton® / Nomex® duplex laminates are multi-layer materials designed to meet the most demanding requirements in terms of heat resistance, electrical insulation and durability. The combination of Kapton® polyimide film and Nomex® aramid paper provides a high-performance solution suitable for critical industrial applications.

These laminates are particularly widely used in the energy, advanced electronics and rail sectors, where components are subjected to extreme temperatures, high electrical stresses and harsh environments.

At ADDEV Materials, we support manufacturers in selecting and custom-processing technical laminates to optimise their performance and integration into applications.

Laminated Kapton Nomex

Structure and composition of Kapton® / Nomex® laminate

The Kapton® / Nomex® laminate is based on a high-end technical structure:

  • Kapton® → thermal resistance and stability
  • Nomex® → electrical insulation

This combination allows for an extremely high-performing material to be obtained.

Duplex laminates offer an optimised solution:

  • duplex → 2 couches, high-performance and controlled solution
  • triplex → 3-ply, enhanced performance

The Kapton® / Nomex® duplex is particularly suited for applications requiring high performance without excessive complexity.

What is a Kapton® / Nomex® duplex laminate?

A duplex Kapton® / Nomex® laminate is a material composed of two layers:

  • a Kapton® (polyimide) layer providing extreme heat resistance and exceptional stability
  • a layer of Nomex® (aramid) providing high-performance electrical insulation

This combination allows for the achievement of:

  • resistance to very high temperatures
  • reliable electrical insulation in extreme conditions
  • exceptional durability

This is an ideal solution for critical industrial applications.
