XPS Foam Sandwich Core provides a practical way to reduce the weight of composite and sandwich panels while maintaining useful structural thickness. This is particularly valuable for large panels where using a completely solid material would result in excessive weight.
The closed-cell structure of XPS foam also provides relatively low water absorption and useful thermal insulation properties. These characteristics can be beneficial in construction panels and certain industrial applications where moisture resistance and thermal performance are required.
XPS Foam Sandwich Core can be combined with FRP, fiberglass, aluminum, and other face-sheet materials. After bonding, the materials form an integrated sandwich structure in which the face sheets carry the primary tensile and compressive loads and the core supports the skins and carries part of the shear load.
The core density and thickness should be optimized according to the final application. A very low-density core may reduce weight but may not provide sufficient compression or shear performance, while a very high-density core may add unnecessary weight and cost.
For professional buyers, the evaluation should include density, thickness, compressive strength, shear performance, water absorption, dimensional stability, processing characteristics, adhesive compatibility, and material consistency.
