The incorporation of particulate fillers such as quartz and marble into rigid polyurethane (PU) foams can significantly alter their mechanical, thermal, and acoustic properties. This study investigates the influence of quartz and marble as fillers on the performance of rigid PU foams. The effects of varying filler concentrations on the foams’ compressive strength, thermal conductivity, and structural integrity are evaluated. The findings suggest that both quartz and marble fillers enhance the mechanical strength of the foams, with marble providing superior results in terms of thermal conductivity. However, the presence of fillers also leads to a decrease in foam flexibility and an increase in density. These results offer valuable insights into optimizing the properties of rigid PU foams for applications in construction, insulation, and automotive industries.
