Thermally expanded graphite oxide

Borosilicate glass is a range of glasses based on boric oxide, silica, and a metal oxide. It has excellent thermal shock resistance and chemical resistance. A recent patent claimed the use of borosilicate glass powder (50-100 phr) in conjunction with expandable graphite (100 phr) or vermiculite in polyolefin, epoxy, or elastomers to achieve good fire retardancy (as evidenced by the Cone Calorimeter test at 35 kW/m2).99... 

Very effective flame retardant data were obtained with styrene-butyl acrylate copolymer/graphite oxide (St-BA/GO) nanocomposites. "- The GO was prepared by oxidation of expandable graphite, and the St-BA/GO nanocomposites (GO content of up to 4% mass fraction) were synthesized by exfoliation- adsorption of monomer followed by in situ emulsion polymerization. The distribution of the GO particles was examined by XRD, TEM, and electron diffraction exfoliated GO layers in crystalline structures were observed. The thermo-gravimetric analysis (TGA) data show a slight increase in thermal stability (up to 15°C with a 3% mass fraction of GO). Significant reduction in heat release rate by increasing GO content has been reported all nanocomposites reduced about 40% of total heat released compared with that of St-BA, as shown in Figures 10.14 and 10.15.
