In this research, flame-retardant rigid polyurethane foams (PUFs) were prepared using free foaming by combining molybdenum trioxide (MoO3) nanoparticles with polyol polyester obtained from soybean oil and 4-'4-diphenylmethane diisocyanate polymer (MDI polymer). Due to the reduction of oil reserves and the environmental problems of these materials, it is necessary to find a suitable alternative for synthesizing polyols. The chemical structure of polyol obtained from soybean oil was identified by proton nuclear magnetic resonance spectroscopy (1H-NMR) and Fourier transform infrared (FT-IR). Morphology, physical-mechanical properties, thermal stability, and flammability of polyurethane foams modified with MoO3 nanoparticles were investigated. The results showed that combining MoO3 nanoparticles with PUF increases the density, compressive strength, and thermal stability due to the high mechanical properties and flame retardancy of MoO3 nanoparticles.
