Duplex Aluminium / PET Laminates: Insulation and protection solutions

Alu/PET laminates are multilayer materials designed to ensure a high electrical insulation, mechanical protection and excellent dimensional stability. Thanks to the combination of an aluminium layer and a PET film, they offer an optimal balance between Rigidity, resistance and electrical performance.

These laminates are particularly suitable for industrial applications requiring High reliability in constrained environments, including in electronics, energy or railways.

At ADDEV Materials, we support manufacturers in the custom selection and transformation of technical laminates, in order to optimise their performance and integration into applications.

Alu PET laminate

Structure and composition of Alu/PET laminate

The Alu/PET laminate is based on a high-performance technical structure:

  • aluminium → EMI shielding and conductivity
  • PET → isolation, stability and mechanical strength

PET offers better dimensional stability than other polymers.

Duplex laminates are designed to offer a simple and effective solution:

  • duplex → 2 couches, optimised solution
  • 3 layers, enhanced performance but more complex

The Alu / PET duplex is ideal for applications requiring controlled stability and performance.

What is an aluminium/PET laminate?

A duplex laminate of Aluminium / PET is a material made up of two layers:

  • an aluminium layer ensuring conductivity and EMI shielding
  • a PET (polyester) layer providing insulation and dimensional stability

This combination allows for the achievement of:

  • a Excellent rigidity
  • a good thermal resistance
  • a Reliable electrical isolation

This is an ideal solution for applications requiring precision and stability.

Laminated Aluminium / PET vs. Other Materials: What's the Difference?

The Alu/PET laminate is distinguished by its stability and robustness.

Laminated Alu/PET vs Alu/CoPo

  • Alu / PET → Improved dimensional stability
  • Alu / CoPo → more flexible

Alu / PET Laminate vs Nomex Laminate

  • Alu / PET → improved rigidity
  • Nomex → best extreme thermal resistance

Aluminium Laminates / PET vs Technical Films

  • laminated → higher performing multi-layer solution
  • film → simple but less complete solution

In a nutshell
