XPS Panel Core is used as the lightweight internal core of composite panels and sandwich panels. Its main purpose is to support the outer skins, increase the overall panel thickness, and improve bending stiffness while maintaining relatively low weight.
XPS Panel Core can be combined with aluminum sheets, FRP, fiberglass-reinforced plastic, decorative skins, and other materials. The face sheets provide the main surface and structural functions, while the core provides internal support and maintains the spacing between the skins.
For building-related applications, XPS may also provide useful thermal insulation properties. However, if a project has a specific fire-rating requirement, the complete panel system must be evaluated according to applicable building codes and certification requirements. The fire performance of a finished sandwich panel should not be assumed solely from the name of the core material.
When purchasing XPS Panel Core, buyers should specify density, thickness, sheet dimensions, thickness tolerance, compressive strength, thermal conductivity, water absorption, and surface requirements.
For automated composite-panel production, dimensional accuracy is particularly important. Consistent sheet dimensions and thickness can help improve bonding quality, reduce material waste, and increase production efficiency.
