PET (Polyethylene Terephthalate) foam board. It is made by mixing PET resin with foaming agent, and then processed through extrusion, foaming and calendaring. The rigid PET foam board used on the composite panel is harder and denser.
Characteristics of PET Foam Board
- Rigid Characteristics
Compared with other foam materials, PET foam board is harder and denser. It usually won’t bend or deform as easily as regular Styrofoam. - High Density
Its higher density makes it more suitable for applications requiring higher strength and stiffness. - Thermal Insulation Properties
Like other foam materials, PET foam board also has good insulating properties and is suitable for thermal and acoustic insulation applications. - Recyclability
PET foam is recyclable, which is good for the environment.

Processing of PET Foam Board
PET foam has excellent properties of being easily cut to fit different shapes and sizes. For example, the foam can be cut into sheets, blocks, or custom shapes.
