Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your original research to this Special Issue of Polymers entitled, “Advances in Flame-Retardant and Heat-Resistant Polymeric Materials”. With the expansion of the application range of polymer materials, higher requirements are put forward for the fire safety of composite materials, the durability of flame retardants, the non-toxic and environmental protection of combustion smoke, and the heat resistance of composite materials in practical applications. Therefore, this Special Issue aims to provide an excellent opportunity to explore and publish articles related to the flame retardancy and heat resistance of polymer materials, including, but not limited to, related research on flame retardancy, smoke suppression, thermal protection, and heat resistance of polymer composites.

This Special Issue is open to researchers and authors who wish to submit research and review articles to explore experimental and numerical analysis in these fields. We encourage manuscripts containing scientific discoveries in a wide range of areas of polymer flame-retardant and heat-resistant materials.

In this work, we report the effect of combining styrene-vinyl tetrazole copolymer (StVTz) and ammonium polyphosphate (APP) on the thermal degradation, mechanical properties, flame retardancy, and char formation of low-density polyethylene with ethyl vinyl acetate (LDPE/EVA) composites. The tetrazole heterocycle exhibits high thermal stability (>200 °C), and during its thermal decomposition, it releases non-toxic nitrogen gas. Its degradation generates reactive species capable of cross-linking the polymer chains, thereby promoting the formation of a protective char layer. To evaluate the influence of composition on the intumescent flame-retardant (IFR) properties of LDPE/EVA blends, different concentrations of APP and StVTz additives were incorporated. The composites were prepared in an internal mixer (Brabender Intelli-Torque Plasti-Corder). Test specimens were obtained by compression molding and subsequently cut into appropriate shapes for each analysis. Thermal stability was studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Mechanical properties were evaluated by tensile testing. Morphology of cone calorimetry (CC) residues was examined using SEM. Flammability properties, studied using CC, revealed a 70% reduction in the peak heat release rate (pHRR) and a 48% reduction in the total heat release (THR) compared to the neat LDPE/EVA blend. These results indicate that StVTz and APP act synergistically to improve the flame-retardant properties of LDPE/EVA. Full article
