  • Characterization of commercial expandable graphite fire retardants 
    Focke, Walter Wilhelm; Badenhorst, Heinrich; Mhike, Washington; Kruger, Hermanus Joachim; Lombaard, Dewan (Elsevier, 2014-05)
    Thermal analysis and other techniques were employed to characterize two expandable graphite samples. The expansion onset temperatures of the expandable graphite’s were ca. 220 °C and 300 °C respectively. The key finding ...
  • Flexible PVC flame retarded with expandable graphite 
    Focke, Walter Wilhelm; Muiambo, H.F. (Herminio Francisco); Mhike, Washington; Kruger, Hermanus Joachim; Ofosu, Osei (Elsevier, 2014-02)
    The utility of expandable graphite as a flame retardant for PVC, plasticized with 60 phr of a phosphate ester, was investigated. Cone calorimeter results, at a radiant flux of 35 kW m-2, revealed that adding only 5 wt.% ...
