PET Foam Sandwich Panels
Lightweight, Durable, Eco-friendly
PET foam sandwich panels are a new type of foam composite panel. Compared with other common foam sandwich panels (such as polystyrene (EPS) and polyurethane (PU) foam panels), it not only performs well in performance, but also has significant environmental protection and recyclability advantages. Therefore, it has been widely used in many industries. It is made of polyethylene terephthalate (PET) foam as the core material, combined with different types of skin materials (such as metal, fiber reinforced plastic, aluminum foil, wood, etc.) to form a lightweight, high-strength, excellent thermal insulation and sound insulation composite panel.

Structural Diagram
As a composite material that is both lightweight and high-performance, the classic three-layer structure (facing – core – facing) of PET sandwich panels is the core design to achieve structural stability and functional diversity. This composite form seems simple, but through the synergy of each layer of material, it achieves an efficient balance in mechanical properties, lightweight and application adaptability.
Common Applications of PET Foam Sandwich Panels
Truck Bodies
Box truck bodies made of fiberglass facing PET sandwich panels are light, strong and durable.
Public Transportations
In buses, subways, high-speed trains and other means of transportation, fiberglass facing PET foam sandwich panels are used in floors and other parts to reduce the weight of the vehicle.
RVs
Fiberglass facing PET sandwich panels are used as wall panels, and Plywood facing PET sandwich panels are used as floors.
Furniture
PVC/PET facing PET foam sandwich panels are used in the production of modular furniture (such as partitions, bookcases, desktops, bed frames, cabinets, bathroom wall panels, etc.).
