High Density XPS Core is generally considered when a composite or sandwich structure requires higher compressive performance, greater core support, or improved dimensional stability.
Compared with lower-density XPS cores, a high-density core can generally provide higher mechanical performance, but it also increases material weight and cost. Therefore, choosing a high-density material should be based on actual structural requirements rather than simply selecting the highest available density.
High Density XPS Core may be appropriate for panels exposed to higher surface pressure, local loads, compression, or demanding structural conditions. In these situations, compressive strength and shear performance become particularly important.
However, the overall performance of a sandwich panel depends on the complete structure. Face-sheet strength, core thickness, adhesive performance, bonding quality, panel geometry, and manufacturing process all contribute to the final result.
When purchasing High Density XPS Core, buyers should request technical data covering density, compressive strength, shear performance, water absorption, thermal conductivity, dimensional stability, thickness tolerance, and surface condition.
Prototype testing is recommended for new applications. Selecting the correct density based on engineering calculations can often provide a better balance of weight, performance, and cost than simply choosing the highest-density product.
