Rigid XPS Core is an XPS foam core with relatively high rigidity and dimensional stability. It is commonly used in sandwich panels where the core needs to provide stable support to the outer skins while maintaining a lightweight structure.
In a sandwich panel, the Rigid XPS Core is positioned between two face sheets and bonded using an appropriate adhesive. The core maintains the spacing between the skins and carries part of the compression and shear loads. This can improve the overall bending efficiency of the panel.
One advantage of Rigid XPS Core is its closed-cell structure, which can provide relatively low water absorption and useful thermal insulation properties. These characteristics may be beneficial in certain building and industrial applications.
However, the correct core specification should always be selected according to the final product requirements. Important factors include density, compressive strength, core thickness, dimensional stability, water absorption, thermal conductivity, surface condition, and adhesive compatibility.
For applications involving CNC machining, grooving, drilling, or shaped components, buyers should also confirm the machining characteristics and dimensional tolerances of the Rigid XPS Core.
