“…1 In the literature, ZnB was used solely as flame retardant additive in polyvinylchloride 2,3 and polyurethane. 4 It was used as synergistic additive with intumescent, [5][6][7][8][9] phosphorus, [10][11][12][13][14][15] silicon, 16 and mineral-based flame retardants [17][18][19][20][21][22] in various matrix materials including polypropylene (PP), 5,6,8,9,17,19 polyethylene, 7 polycarbonate, 10,15,16 poly(methyl methacrylate), 11 epoxy resin, 12 polyamide, 13,14 ethylene propylene diene copolymer, 18 and ethylene vinyl acetate (EVA).

Summary The effect of zinc borate (ZnB) was studied on the flame retardant and thermal properties of thermoplastic polyurethane containing huntite‐hydromagnesite. The flame retardant properties of thermoplastic polyurethane–based composites were investigated using limiting oxygen index, vertical burning test (UL 94), thermogravimetric analysis, and mass loss calorimeter. No remarkable effect of ZnB was observed on the flammability properties of composites. UL 94 rating did not change regardless of the added amount of ZnB, and the slight increase in limiting oxygen index value was observed at ratio of 1:1. The adjuvant effect of ZnB was observed during the mass loss calorimeter studies by increasing the barrier effect of the residue in the condensed phase and by increasing the formation of incombustible gasses in the gas phase. The highest fire performance was achieved at ratio of 1:1.

“…This was because of the fact that the low bond energy of P–O reduced the activation energies of the resin . The better thermal stability of AlOOH (as shown in Figure , the weight loss of AlOOH after 484°C was minuscule) made up for the defects in the initial degradation temperature reduction . In addition, T max of DOPO−GPTS with phosphorus and silicon was 479°C.…”

To improve the liquid oxygen compatibility and cryogenic mechanical properties of epoxy resin, we synthesized and characterized a hybrid compound (functionalized boehmite) containing boehmite, phosphorus, and silicon element. The thermal properties and liquid oxygen compatibility of the composites were investigated in detail. The results show that the addition of functionalized boehmite increased the char residue obviously but had little effect on the thermal decomposition temperature and glass-transition temperature of the composites. The liquid oxygen compatibility of the composites was significantly improved. Composites with 4 wt % boehmite, 0.99 wt % Si, and 1.1 wt % P passed the impact test. Surface element analyses before and after the drop tests suggested that the functionalized boehmite in epoxy might have prevented the impact reaction in liquid oxygen through two steps. First, the compound decomposed into phosphoric oxyacid and Al 2 O 3 under the impact energy and captured the H• and •OH radicals produced from the decomposition of the resin. Then, the decomposition covered the surface, forming a protective layer to isolate the oxygen. The mechanism of the liquid oxygen compatibility of the epoxy composites was subsequently analyzed. In addition, the cryogenic tensile properties of the epoxy composites containing functionalized boehmite showed that the composites had potential applications under cryogenic liquid oxygen environments.
