Abstract
In this work, a comparative assessment was conducted to evaluate the influence of organic cork (K) and inorganic microspheres (M), as well as their modification with liquid glass (LG), on the flammability of rigid polyurethane foams (RPUFs). Composites containing 10 wt.% filler were examined through morphology analysis, thermogravimetric testing (TGA), limiting oxygen index (LOI), cone calorimetry, and smoke and toxic gas emission measurements. The study demonstrated that LG modification significantly affected the thermal degradation and combustion behaviour of the foams. LG-coated cork showed reduced calorific value and carbon content, leading to improved fire resistance. In contrast, LG-treated microspheres had a smaller impact on basic combustion parameters but substantially reduced smoke intensity and toxic gas emissions (CO, CO₂), particularly in the RPUF_4M sample. LG application also decreased combustion duration and the emission of harmful combustion products. Overall, this work shows that modifying fillers with LG can effectively enhance the fire safety of polyurethane foams. Among the tested systems, LG-modified microspheres offered the most advantageous balance of thermal stability and reduced smoke generation, highlighting the importance of both filler selection and modification strategy for optimising RPUF fire performance.
