Bio-based phosphorus flame retardants offer significant promise in enhancing the flame retardancy of bioplastics without compromising their environmental friendliness. In this study, a bio-based phosphorus-based flame retardant (PFR) synthesized from epoxidized soybean oil polyol (PESO) was used to enhance the flame-retardant properties of poly(lactic acid) (PLA), aiming to establish the correlation between phosphorus content and the fire behavior of PLA composites. Notably, the study determined that the critical phosphorus content value for improving the PLA rating from NR to V-0 was as low as 0.1 wt % in the composites, with the limited oxygen index (LOI) of PLA increasing from 21.0% to 25.2%. Meanwhile, the introduction of PESO with high phosphorus contents decreased the peak heat release rate (PHRR) and total heat release (THR) of PLA by 5.33% and 9.66%, respectively. Nevertheless, with the complete replacement of the epoxy group by phosphorus ring-opening, PESO loses its plasticizing effect, making it challenging to enhance the elongation at the break of PLA. Finally, the flame-retardant mechanism of PLA/PESO composites was comprehensively analyzed. It was found that the mechanism was also related to the phosphorus contents; high phosphorus was not favorable for the char forming in the condensed phase but promoting the melt dripping and formation of PO • , PO 2• , and HPO • which could trap radicals in the gas phase. This study provides valuable insights into designing PFRs from renewable resources for PLA.

The objective of the present study is to synthesize semi‐rigid polyurethane foam/expanded perlite (SrPUF/EP) composites using different amounts of EP, a natural and environmentally friendly alternative to traditional halogen‐containing flame‐retardants in a one‐step process. This study investigates the mechanical, physical, thermal, and morphological properties, as well as the flame‐retardant and smoke release behaviors of composites. The cone calorimetry test results indicated that the amounts of carbon monoxide and carbon dioxide released during combustion process decreased by 43% and 37%, respectively, in the 8% EP‐added SrPUF/EP composite (4SrPUF). The amount of char residue formed after complete combustion of 4SrPUF composite was found to be 2.7 times higher than that of pure SrPUF. In the UL‐94 test, it was observed that when 4% or more EP was added to SrPUF, the liquid dripping during combustion ceased entirely, and after complete combustion, the main structure remained in the form of char without disintegration. The flexural strength of 1SrPUF, 2SrPUF, and 3SrPUF exhibited increases of 62%, 69%, and 121%, respectively, in comparison to SrPUF (47.15 kPa). The results of this study indicate that EP has the potential to serve as an environmentally friendly and cost‐effective flame‐retardant, thereby enhancing the fire resistance properties of SrPUF.
