TL;DR: An inorganic flame retardant, magnesium hydroxide (MH) with series synergists including melamine (ME), linear novolac resin (LNR), and triphenyl phosphate (TPP) was incorporated with polyformaldehyde (POM) resin in this paper.
Abstract: An inorganic flame retardant, magnesium hydroxide (MH) with series synergists including melamine (ME), linear novolac resin (LNR), and triphenyl phosphate (TPP) was incorporated with polyformaldehyde (POM) resin in this article. The obvious advantage of the system is that the used flame retardant and the synergists possess multiflame retarding mechanisms and multifunctions. The prepared flame retardant POM could achieve UL94 V-0 rating (1.6 mm) with optimum flame retardant/synergists formulations, showing satisfactory flame retardance. Various characterization methods including pyrolysis-gas chromatogram-mass spectrometer (Py-GC-MS) analysis, scanning electron microscope (SEM) observation, and thermogravimetric analysis (TGA), were used to investigate the interaction among the components and reveal the corresponding synergistic mechanisms. © 2011 Wiley Periodicals, Inc.

TL;DR: In this paper, the thermal degradation and combustion of UHMWPE doped with triphenyl phosphate (TPP) at atmospheric pressure was studied by molecular beam mass spectrometry.
Abstract: The thermal degradation and combustion of ultra-high-molecular-weight polyethylene (UHMWPE) doped with triphenyl phosphate (TPP) at atmospheric pressure was studied by molecular beam mass spectrometry, dynamic mass spectrometric thermal analysis, microthermocouples, thermogravimetry, gas chromatography/mass spectrometry.

The effective values of the rate constant and activation energy of the thermal degradation reaction were determined. Burning velocity and temperature profiles in UHMWPE and UHMWPE + TPP flames were measured. The composition of the combustion products in a flame zone adjacent to the burning surface of the sample was determined. TPP vapor in the flame was detected. The addition of TPP to UHMWPE was found to reduce the flammability of the polymer. It is shown that TPP acts as a fire retardant in both the condensed and gas phases.

TL;DR: In this article, a self-extinguishing HDPE/EPDM/boron carbide/triphenyl phosphate blend was successfully fabricated with more than 21% LOI.
Abstract: It was known that triphenyl phosphate wasn't homogeneously dispersed in HDPE/EPDM/boron carbide blends, which caused the decrease in mechanical properties. HDPE, EPDM, boron carbide, and triphenyl phosphate were blended with PE-g-MAH(polyethylene-graft-maleic anhydride) as a compatiblizer for improving the miscibility of triphenyl phosphate. Tensile strength of HDPE/EPDM/boron carbide blends decreased with increasing the contents of triphenyl phosphate for flammability. However, the mechanical properties of HDPE/EPDM/boron carbide/triphenyl phosphate blends increased by the addition of compatiblizer because triphenyl phosphate was homogeneously mixed in the blend system. The homogeneous dispersibility of triphenyl phosphate was confirmed by using scanning electron microscopy (SEM). Increased thermal stability and flammability derived from high miscibility of triphenyl phosphate were confirmed by the results of thermogravimetric analysis (TGA) and limiting oxygen index (LOI). A self-extinguishing HDPE/EPDM/boron carbide/triphenyl phosphate blend was successfully fabricated with more than 21% LOI.

TL;DR: In this article, an encompassing investigation of the solubility and mass transfer coefficient enhancement of triphenyl phosphate through hydrotropy has been undertaken, where the effectiveness of hydrotropes was measured by the determination of Setschenow constant “Ks.
Abstract: An encompassing investigation of the solubility and mass transfer coefficient enhancement of triphenyl phosphate through hydrotropy has been undertaken. The solubility studies have been carried out with hydrotropes such as potassium xylene sulfonate, ammonium xylene sulfonate, calcium xylene sulfonate, for a wide concentration range from 0 to 3.0 mol/L along with system temperature from 303K to 333 K. The effectiveness of hydrotropes was measured by the determination of Setschenow constant “Ks”. The solubility of triphenyl phosphate increases with increasing hydrotrope concentration and also with system temperature. A minimum hydrotrope concentration (MHC) in the aqueous phase was required to initiate significant solubilization of triphenyl phosphate. Consequent to the increase in solubilization of triphenyl phosphate, the mass transfer coefficient was also found to increase with increasing hydrotrope concentration. A threshold value of MHC is to be affirmed to have an appreciable enhancement in the mass transfer coefficient. The maximum enhancement factor, which is the ratio of the solubility values in the presence and absence of a hydrotrope, has been determined for all sets of experiments. Chemical Engineering
