The compressive strength of rigid foams depends on cell density, manufacturing method, polymer type, and the quality of cell distribution. Foams with uniform, closed-cell structures generally support heavier loads. For example, Extruded Polystyrene Foam is manufactured via a continuous extrusion process that yields exceptionally consistent cell morphology, which directly improves its ability to resist deformation under pressure. Environmental factors—such as sustained load duration and temperature—also affect long-term creep performance. Engineers typically select high-density grades for industrial flooring, heavy vehicle loads, or infrastructure applications where structural stability is essential.
