“…When the sample was exposed to flame, EG could form worm-like graphite and form a physical insulation layer on the surface of the sample [22,23]. When HPCTP was exposed to flame, it generated water, nitrogen oxides, carbon oxides , and phosphorus free radicals to dilute the flammable gas, but it also instantly released these products due to the generation of a large amount of gas, resulting in a large HRR [29,30,39], as shown in figure 3. However, the phosphoric acid produced by HPCTP pyrolysis could accelerate the cleavage of silicon-oxygen bonds to form a protective layer of silicon dioxide on the surface of the sample, thereby inhibiting the combustion of the sample [40], at the same time, the decomposition amount of silicone rubber foam is increased, so the THR of SiF-EG15% -HPCTP0% is the best.…”

Silicone rubber foam (SiF) with EG/HPCTP was prepared by high-temperature vulcanization. The flame retardancy of SiF was evaluated using the LOI (limiting oxygen index), UL-94, cone calorimetry test (CCT), thermogravimetric analysis (TGA), and mechanical properties. The results showed that EG/HPCTP could improve the LOI of SiF, and the SiF could pass the UL-94 V-0 rating. Compared with pristine SiF, EG/HPCTP could reduce the total heat release rate (THR), heat release rate (PHRR). Digital images of the char residues showed that the HPCTP was beneficial to promote the strength of SiF with EG. TGA showed that the branched decomposition temperature and main chain pyrolysis temperature of SiF were delayed. Mechanical properties analysis showed that EG and HPCTP could improve the mechanical properties of SiF. These indicated that the addition of EG/HPCTP was a good approach to prepare high effective flame-retarding SiF.

“…The ignition time was delayed by 75 s, and the residual carbon and LOI were improved. Wang et al [29] studied the effect of HPCTP on viscose fibers. The addition of HPCTP can improve the LOI of viscose fibers and form a carbon layer on the surface of the fibers to improve the flame retardancy of viscose fibers.…”

“…phosphorous of PA-FR degraded to form polyphosphoric acid leading to the dehydration of nylon fabric, and they covered the surface of the fiber and generated a cover layer. 20,21 In addition, PA-FR also degraded to form sulfur atom which maybe react with amine end-groups or carboxylic acid end-groups, or attack polyamide linkage by nucleophilic reaction. Then, the phosphorus, nitrogen and sulfur in PA-FR decomposed volatile glutinous compounds forming a layer membranous substance on the surface of nylon fabric at high temperature, which could prevent oxygen from separating to reaction zero and isolate the contact between fire and nylon fabric.…”

Monomer of polyamide (PA66) and flame-retardant intermediate product (FR) were firstly synthesized, and the flame-retardant (PA-FR) was further gained by polymerization of PA66 and FR. The structure of PA-FR was confirmed by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (NMR), X-ray photoelectron spectroscopy (XPS), and gel permeation chromatography (GPC). The thermal properties of PA-FR and the finished fabric were evaluated by thermal gravity analysis (TGA) and differential scanning calorimetry (DSC). Moreover, X-ray diffraction analysis (XRD) showed that melting eutectic reaction occurred between PA-FR and nylon fabric. The experimental results showed that the limiting oxygen index (LOI) value of PA-FR treated fabric and PA-FR treated fabric after 10 laundries were improved to 28.8% and 26.4%, respectively. It implied that PA-FR had a good and durable function of imparting fire-resistance to nylon fabric.

“…In addition, carbon residue and limiting oxygen index of composites have been improved. Wang [ 25 ] found that the HPCTP can increase the limiting oxygen index of viscose fiber and form carbon layer on the fiber surface, which improves the flame resistance of viscose fiber. Shen [ 26 ] used magnesium hydroxide and HPCTP as flame retardants to study the synergistic flame retardants of magnesium hydroxide and HPCTP to ethylene‐vinyl acetate copolymer.…”

Hexaphenoxycyclotriphosphazene (HPCTP), modified with phenoxy groups based on hexachlorocyclotriphosphazene (HCCP), has been proved that have excellent thermal stability. In this article, HPCTP and glass fiber (GF) were added into the rigid polyurethane foam (RPUF) to improve the flame‐retardant and mechanical properties of RPUF. The mechanical properties of composite were measured by compressive strength test. The micrographs were observed by scanning electron microscopy. Furthermore, the flame‐retardant and thermal properties were investigated by limiting oxygen index, cone calorimeter test, and thermogravimetric analysis. The results showed that the addition of HPCTP and GF would improve the mechanical and flame‐retardant properties of RPUF.
