    Rigid polyurethane foams (RPUF) with nanoporous graphene (NPG) were synthesized and their properties, including density, mechanical, morphological, and thermal‐resistant properties were studied. In the current work, polyols of the RPUF formulation were Flame‐retardant rigid polyurethane foams (RPUFs) with DPPM (DPPM‐RPUF) as fire‐retardant additive were prepared. Scanning electron microscope (SEM) and mechanical performance testing showed that DPPM exhibited a favorable compatibility with RPUF and negligibly negative influence on the mechanical properties of ://

Therefore, it is of great importance to study the thermal degradation behaviors and mechanisms of PUFs.

Basic research shows polyurethane foam (PUFs) pyrolysis is a complex process, which includes a Due to its excellent performance, the rigid polyurethane has been widely used in the building construction nowdays.

In this study, the fire phenomena of RPUFs were investigated using /_Fire_Phenomena_of_Rigid_Polyurethane_Foams. While perfluoroalkane (PFA), a liquid state nucleating agent for a rigid polyurethane foam (RPUF) to enhance the thermal insulation property, has the excellent nucleating characteristics, it is very expensive as well as environmentally harmful due to the fluoride compound.
