“…However, the disadvantages of IFR systems are restricted as a result of their poor FR efficiency comparing to halogen containing FRs, their poor compatibility with matrix system and lower thermal stability. To overcome these problems, researchers aim to develop oligomeric or polymeric IFRs with relatively higher molecular weight and synergistic agent to enhance flame retardancy of IFR …”

In this study, mixing petroleum-based low-density polyethylene (LDPE) with biodegradable poly(lactic acid) (PLA) is used as polymer matrix. Boron compounds, metal hydroxides, melamine (MLM), ammonium polyphosphate (APP), and pentaerythritol (PER) were used as reinforcement materials to improve flame resistance of polymer matrix. The composite materials were characterized by Fourier transform infrared spectroscopy, limiting oxygen index (LOI), thermogravimetric analysis, mechanical test, and scanning electron microscopy analyses. The LOI analysis showed that for samples, which included MLM, APP, and PER, the LOI values were dramatically improved. Especially, the LOI value of sample Q (LDPE80/PLA20/APP30/PER15/MLM15/ZB3) was enhanced about 95.17% compared to polymer mixing.

“… Traditional halogenated flame retardants (HFRs) demonstrate remarkable flame retardance efficiency. However, there are serious disadvantages such as the release of poisonous and corrosive fumes from HFRs during combustion .

A novel curing and flame‐retardant agent (PEPA‐TMAC) was successfully synthesized. The chemical structure was characterized by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR). Use of PEPA‐TMAC as part of the curing agent in combination with another anhydride for a commercial epoxy resin (EP) was studied. Results of differential scanning calorimetry (DSC) indicated that PEPA‐TMAC was an effective curing agent for EP. The dynamic mechanical analysis (DMA) results showed that the glass transition temperature (Tg) and cross‐linking density (Ve) of EP composites exhibited an increase trend with the addition of PEPA‐TMAC. The limiting oxygen index (LOI) value of EP composites reached 26.9%, and the cone calorimeter results indicated that peak heat release rate (PHRR), total heat release (THR), smoke produce rate (SPR), and total smoke produce (TSP) remarkably decreased with increasing PEPA‐TMAC content. TGA data showed that the addition of PEPA‐TMAC greatly increased the amount of residual char during combustion. The morphology of the residual char was studied by SEM and showed that the addition of PEPA‐TMAC greatly increased the stability of EP composites. The thermogravimetric analysis (TGA), energy‐dispersive X‐ray spectroscopy (EDS), and FTIR results revealed the flame‐retardant mechanism that PEPA‐TMAC can promote the formation of charred layers with the phospho‐carbonaceous complexes in the condensed phase during burning of EP composites.

“…PCs find applications in different fields including automotive and the aviation industry, buildings and construction, and windmills as blades [9,[12][13][14][15]. Considering the high-end engineering applications of PCs, the need for bio-based FRPCs with improved flame resistance and excellent mechanical properties cannot be overemphasized [9,16,17]. PLA is a vital bioplastic with excellent properties, but the issue of high flammability and low thermo-mechanical properties has made it inferior compared to the petrochemically derived plastics [18,19].…”

The inherently poor flame retardancy and comparatively low tensile strength of poly(lactic acid) (PLA) have limited its wide adoption as alternative 'green' engineering plastic in many fields. This manuscript reports the synthesis of a new phosphorus flame retardant-phenylphosphonic 3(2-aminobenzothiazole) (P-TAB) and its combination with recycled short wool fibers (WF) for improving the flame retardancy and the mechanical properties of PLA. Fourier transform infrared (FTIR), 1 H, and 13 C nuclear magnetic resonance (NMR) spectra proved that P-TAB was effectively synthesized. Considerable reductions in heat release rate, total heat released, CO and CO 2 produced were attained with 3 wt% P-TAB and various WF loadings. The fire performance index (FPI), and fire growth index (FGI) improved by 38.2 and 48.1% respectively. The composite achieved a V-0 rating at 20 wt% WF loading and an LOI value of 28.5%. TG-IR results showed substantial reductions in evolved gaseous products. The tensile strength and Young's modulus improved significantly with the increasing content of WF in the composite.
