Aluminum laminated PET foam core sandwich panels are composite materials made up of two layers of aluminum sheets bonded to a core material made of PET (polyethylene terephthalate) foam. This sandwich structure combines the lightweight and corrosion-resistant properties of aluminum with the insulating and lightweight nature of PET foam.

Product Advantages

  • Lightweight: It has lightweight properties that reduce the structural load.
  • Anti-corrosion: Aluminum sheets are corrosion-resistant, increasing the service life of the material.
  • Easy to Process: This material is easy to cut, drill and process for easy construction.
  • Environmental Protection: PET foam and aluminum sheets can be recycled and are environmentally friendly products.

Basic Structure

  • Aluminum Sheet: The outer layer of the sandwich panel is made of aluminum sheet. Aluminum was chosen because it is lightweight, corrosion-resistant and easy to fabricate. The surface of aluminum panels can be treated to enhance its durability or provide a specific decorative finish.
  • PET Foam Core: The core material is made of PET foam, which is a lightweight, closed rigid foam. It has high strength, and using PET as the core material can greatly improve the stability of the sandwich panel.
