Polyurethane foams are in general flammable and their flammability can be controlled by adding flame-retardant (FR) materials. Reactive FR have the advantage of making strong bond within the polyurethane chains to provide excellent FR over time without compromising physico-mechanical properties. Here, phenyl phosphonic acid and propylene oxide-based reactive FR polyol was synthesized and used along with limonene based polyol for preparation of FR polyurethanes. All the obtained foams showed higher closed cell content (above 96%). By the addition of FR-polyol, the compressive strength of the foams showed 160% increment which could be due to reactive nature of FR-polyol. Moreover, 1.5 wt % of phosphorus (P) content reduced the self-extinguishing time of the foam from 81 (28% weight loss) to 11.2 s (weight loss of 9.8%). Cone test showed 68.6% reduction in peak heat release rate along with 23.4% reduction in thermal heat release. The change in char structure of carbon after burning was analyzed using Raman spectra which, suggests increment in the graphitic phase of the carbon over increased concentration of phosphorus. It can be concluded from this study that phosphorous based polyol could be blended with bio-based polyols to prepare highly FR and superior physico-mechanical rigid polyurethane foams.

“…Cardanol with abundant sources, low price, and excellent performance attracts the attention of researchers. There are many modified products, such as cardanol phenolic resin, cardanol-based epoxy resin, cardanol-based surfactants, polyepoxy-cardanol glycidyl ether, and so on, which are widely used in toughening [19][20][21], flame retardant [22], coating [23], adhesive [24,25], curing agents [26] and many other industrial fields. This attracts researchers' attention to study cardanol potential applications in the rubber industry [27].…”

“…To attain acceptable levels of flame retardancy, 40 wt % of chloride and 20 wt % of bromide are needed. 49 Hence, to decrease the halogen concentration and to improve FR properties, various metallic compounds, such as metal oxides, can be utilized as synergists and among these, antimony trioxide acts as an inhibitor in the gas phase. The other commonly used synergists are zinc, nitrogen, phosphorus, and tin compounds.…”

The work presented in this paper deals with the comparative synthesis of diglycidyl ether-based tetrabromobisphenol-A(TBBPA) using both conventional and nonconventional methods in order to explore materials for better industrial applications with respect to effective yield, cost, and time consideration. The conventional method involved the polycondensation of TBBPA and epichlorohydrin in the presence of an alkali catalyst. The nonconventional routes adopted for the synthesis of the material involved ultrasonication, microwave irradiation, and UV light exposure. The Fourier transform infrared spectroscopy spectra of all the synthesized materials of the resin were found to be identical, and the X-ray diffraction analysis showed the material as amorphous. The mechanical studies of the resins revealed that all these resins synthesized by different methods are strong and possess high viscosity. Based on the overall thermal, rheological, and excellent hydrophobic properties, it can serve as an excellent flame retardant.
