  • Characterizing CaCO3 particle dispersion in blown film 
    Radebe, Lucky; Wesley-Smith, James; Focke, Walter Wilhelm; Ramjee, Shatish (De Gruyter, 2023-01)
    A novel method for the visualization and quantification of the state of dispersion of calcium carbonate particles in thin blown polymer films is described. Particle imaging was achieved by elemental mapping using energy ...
  • Formulating calcium carbonate masterbatches 
    Radebe, Lucky; Wesley-Smith, James; Focke, Walter Wilhelm; Ramjee, Shatish (De Gruyter, 2023-01)
    The effects of filler content, filler particle size and surface coating, as well as the natures of the wax and metal stearate lubricants on the properties of calcium carbonate-filled linear low-density polyethylene compounds ...
  • Thermal characterisation of metal stearate lubricant mixtures for polymer compounding applications 
    Phillips, Justin; Weldhagen, Michelle; Mhlabeni, Thobile; Radebe, Lucky; Ramjee, Shatish; Wesley-Smith, James; Atanasova, Maria T.; Focke, Walter Wilhelm (Elsevier, 2021-05)
    Metal stearate blends are potential lubricants and filler dispersants in polymer compounding. Therefore, the thermal phase behaviour of binary blends of calcium stearate and magnesium stearate with zinc stearate was ...
