Summary: The article focuses on the development of customized polyolefin formulations with low flammability and high weathering resistance to provide value-added polyethylene grades with extended service lifetime. The compounds achieved V0 classification in UL94V flammability tests while maintaining mechanical properties to a large extent, showing promise for outdoor applications where long-term weathering stability and flame retardance are important.

Summary: This study investigated the density-dependent burning behavior of commercial bead foams using cone calorimetry, highlighting the importance of density in predicting thermal loads. The peak heat release rate of flame-retarded EPP and E-mPPE was found not to be dependent on density, indicating an increased homogeneity by addition of flame retardant.

Summary: The replacement of traditional metallic components with plastic-based materials in the marine sector is currently limited due to mechanical requirements and flammability issues. However, using nanosized organoclays as flame retardants can increase the mechanical properties of polymer nanocomposites and meet nonflammability requirements.

Summary: This study investigated the effect of different concentrations of an intumescent formulation and montmorillonite on the fire behavior of polylactic acid composites. The results showed that the addition of the intumescent formulation and montmorillonite improved the fire-retardant performance of the composites, with the highest AP concentration (17%) and the lowest ANa concentration (1.2%) achieving the best result.

Summary: In this study, novel hybrid flame retardants containing zinc hydroxystannate and carbon nanotubes (ZHS-CNTs) were synthesized and their structure and morphology were characterized. The flame-retardant and smoke inhibition performance of composites incorporating ZHS, CNTs, and ZHS-CNTs into epoxy resin (EP) were compared and studied. It was found that the EP/ZHS-CNT composites showed the highest improvements in fire resistance and smoke inhibition properties. The synergistic effects between ZHS and CNTs, catalyzing effect of ZHS, and stable network structure of CNTs contributed to the enhanced properties.

Summary: Polyoxymethylene (POM) nanocomposites reinforced with synthetic wollastonite nanofibers (SWN) showed improved mechanical, thermal, and flammability properties as the aspect ratio of SWN increased. Higher aspect ratio SWN resulted in increased tensile strength, Young's modulus, and impact strength in POM nanocomposites. However, lower aspect ratio SWN performed better in flame retardancy, with delayed time to ignition and decreased peak heat release rate.

Summary: This study investigated the synergistic effects of hybrid nanofillers on the anticorrosion and flame retardancy properties of graphene oxide reinforced epoxy coatings. Testing methods included EIS, Tafel polarization, SST, LOI, and TEM to reveal the improvements in corrosion resistance and burning behavior. The results showed that hybrid nanofillers enhanced the barrier properties of the coatings, leading to better performance in both corrosion protection and flame retardancy.

Summary: A novel P(AN-co-DMVP) copolymer with excellent thermal stability and flame retardance properties was successfully synthesized, showing a significant increase in oxygen index and a decrease in heat release with the addition of DMVP. The relationship between copolymer structures and flame-retardant performance was systematically investigated using various analytical methods, proposing a comprehensive flame-retardant mechanism involving DMVP in both the gaseous and condensed phases.

Summary: This study presents an effective self-intumescent flame retardant system for epoxy resin based on the synergistic effect between Cu2O and ammonium polyphosphate. The optimal mass ratio of Cu2O: APP was found to be 2:8, resulting in improved fire performance of EP. The presence of Cu2O catalyzes char formation and CO to CO2 conversion, leading to decreased heat release and smoke production in EP.
