Fullerene (C 60 ) is one of the most widely noticed nano-fillers because of its high reactivity towards free radicals, called as a "radical sponge."…”

Summary To improve the large release of smoke and heat for brominated flame retardants (BFRs) in fire hazard, fullerene (C60) had been introduced in high density polyethylene (HDPE)/bromine flame retardant (Deca/Sb2O3, BFR in short) system in this study. The effects of C60 on the thermal properties, flame retardant properties, rheological behaviors, and smoke release behaviors in HDPE/BFR blends were researched. During polymer thermal degradation, C60 and BFR exhibited the trapping radical ability in condensed phase and gaseous phase, respectively. The intergrated effects of C60 and BFR on the thermal stability and flammability of HDPE were studied by thermo‐gravimetry and cone calorimeter. It was indicated that the introduction of C60 improved the thermal and thermo‐oxidative stability of HDPE/BFR blends. A remarkable advantage of adding C60 was to reduce the peak heat release rate and the average specific extinction area, especially at higher concentration of C60. The analysis of rheological behaviors and pyrolysis products revealed that C60 can capture alkyl radicals, chain radicals, and bromine radicals in the condensed phase, which was in favor of terminating the thermo‐oxidative decomposition and inhibiting the heat and smoke release of HDPE/BFR blends during combustion.

“…They are used in corporation with antimony trioxide (Sb 2 O 3 ) to enhance the flame retardation (the halogen antimony synergistic). The thermal stability and flammability of EPDM are improved by adding deca-bromo-diphenyloxide (DBDPO) along with antimony trioxide as the acts in a synergy with However, these compounds create interfaces with the polymer matrix leading to the deterioration of both the tensile strength and elongation at break (Montezin et al, 1997;Yu et al, 2004). The halloysite nanotubes (HNT) are made of alumino-silicate clays (Al 2 Si 2 O 5 (OH) 4 ·nH 2 O) with hallow nano-tubular structure.…”

In this work, Halloysite Nanotube (HNT) was synthesized, using a modified method, from kaolin clay. The scanning electron microscopy (SEM) of the synthesized HNT revealed that many of the nanotubes were tubular; however, spherical and semi-spherical, platy and semi rolled structures were also observed. Fire retardant EPDM compounds composed of typical flame retardants (FR), deca-bromo diphenyl oxide (DBDPO), antimony oxide (Sb 2 O 3 ), talc and carbon black were prepared. Three elastomer compounds, with 5, 10 and 20 wt.% of synthesized HNT, and one more compound with 10 wt.% of synthesized HNT and 10 wt.% of conventional flame retardants were prepared and formed by a two roll mill. A TEM micrograph was presented to prove the well dispersion of HNT in polymer matrix. The flammability, thermal stability and tensile strength of the compounds were compared to that of typical fire retarded EPDM. The results showed that the typical flame retardants diminish the tensile strength and elongation at break of EPDM elastomers; in addition, these compounds showed the lowest thermal stability among the typical formulations. The extent of flammability of the compounds was characterized using the cone calorimetry technique. The compound containing 5 wt.% HNT showed the highest tensile strength, the least flammability and the highest thermal stability compared to the other compounds. This was related to the good dispersion and also on the tubular structure of the synthesized nanotubes. The peak of heat release rate (PHRR) and total heat release (THR) as well as the amount of hazardous gas emission for the sample having the highest mechanical response was smaller than those with conventional micro-filler flame retardants.

“…It can be widely used in many fields [1][2][3][4][5][6][7] because its backbone is almost saturated. During outdoor applications, it is degraded by heat [8][9][10], radiation [11][12][13], chemical environment [14][15][16][17] and ozone [18,19], which can cause the loss of bulk properties such as tensile strength and elongation at fracture and result in the reduction of the service life.…”

Ethylene-propylene-diene monomer containing 5-ethylidene-2-norbornene as diene was exposed to artificial weathering environment produced by a xenon lamp light exposure and weathering equipment for different periods of time. The changes of surface color and mechanical properties were monitored by spectrophotometer, computer-controlled tensile testing and hardness measurements. Crosslink density of ethylene-propylenediene monomer specimens was measured by the solvent swell method. The results showed that the surface of ethylene-propylene-diene monomer became yellower due to the form of carbonyl group. The degradation process proceeded predominantly via cross-linking. With increase in crosslink density, the tensile strength increased and the elongation at fracture decreased.
