“…Recently, some specific branched methylphenylsiloxanes were found particularly effective in polycarbonate (PC) and in PC/acrylonitrilebutadrene-styrene (ABS) blends with a low (ABS) content. 79,80 It is believed that due to the inclusion of aromatic groups in the siloxane, it becomes significantly more soluble and more easily dispersed in PC than straight polydimethylsiloxane. It was shown that these siloxanes tend to migrate from the inside of the PC resin to the surface during combustion and accumulate quickly on the surface.…”

“…The presence of nitrogen compounds have had significant effect on flame resistance, as can be seen in the low flammability of wool, silk, and leather (Horacek and Grabner, 1996), triazines, isocyanates, urea, guanidine, and cyanuric acid derivatives are nitrogen-containing organic compounds and have been used as flame retardants (Horacek and Grabner, 1993). Silicon containing flame retardants have also been used (Iji, 1998;Zaikov and Lomakin, 1996). Boron-based compounds have also received extensive usage (Zing de, 1996).…”

Using simple combustion apparatus the effect of wood fibres on the flammability properties of Low Density Polyethylene (LDPE) was studied. Composite samples were prepared with LDPE and Kola Nitida (KN), and LDPE and Alstonia Boonei (AB) with fibre contents of 0, 5, 10, 15, and 20 wt. %. Test results show that ignition time and time for auto-combustion increased with increasing fibre content for both composite types. The flame propagation rate decreased with increasing fibre content for both composite samples. At 20 wt.%, LDPE/KN had about 650% and 1032% increment in ignition time and auto combustion time respectively, and showed a decrease of about 200% in FPR value, while LDPE/AB had about 290 % and 180 % increment in ignition time and auto combustion time respectively, and showed a decrease of about 110% in FPR value. The results show that LDPE/KN composites show better flame retardancy properties over LDPE/AB composites at 20 wt% fibre content.

“…They are endowed with excellent thermal stability and high heat resistance, with very limited release of toxic gases during thermal decomposition. Several types of silicone polymers were applied as flame retardants in polycarbonates (Iji & Serizawa, 1998). For the PC materials modified with branched methyl-and phenylsiloxanes and end-capped by methyl groups, limiting oxygen index (LOI) increased over 35 %, whereas LOI was about 27 % for pure PC.…”
