Duplex PET / Cellulose Laminates: Electrical Insulation and Protection Solutions

PET/cellulose duplex laminates are multi-layer materials designed to provide reliable electrical insulation, mechanical protection and a cost-effective solution for industrial applications. Thanks to the combination of a polyester (PET) film and a cellulose layer, they offer a good balance between performance, flexibility and cost-effectiveness.

These laminates are particularly well suited to applications requiring effective insulation without extreme performance requirements, particularly in the electronics, energy and general industrial sectors.

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

PET cellulose laminate

Structure and composition of PET/Cellulose laminate

The PET/Cellulose laminate is based on a simple and effective structure:

  • PET → rigidity, stability, resistance
  • cellulose → insulation and flexibility

This combination provides a reliable and accessible material.

Duplex laminates offer an optimised solution:

  • duplex → 2 couches, simple and effective solution
  • triplex → 3-ply, enhanced performance

The PET/Cellulose duplex is particularly well-suited to applications requiring a good performance/cost ratio.

What is a PET/Cellulose laminate?

A PET / Cellulose duplex laminate is a material composed of two layers:

  • a PET layer ensuring dimensional stability and mechanical strength
  • a cellulose layer providing electrical insulation and flexibility

This structure allows for the achievement of:

  • effective electrical insulation
  • good flexibility
  • cost-effective

This is a solution suited for standard industrial applications.

Laminated PET / Cellulose vs. other materials: What's the difference?

The PET/Cellulose laminate is positioned as an economical and reliable solution.

Laminated PET/Cellulose vs. Nomex/PET

  • PET / Cellulose → cost-effective solution
  • Nomex / PET → high thermal performance

Laminated PET/Cellulose vs. PET/PET non-woven

  • PET / Cellulose → standard d'isolation
  • Non-woven → vibration absorption

Laminated PET / Cellulose vs. technical films

  • laminated → higher performing multi-layer solution
  • film → simpler solution

In a nutshell
