Author:Kruger, HR; Focke, WW; Mhike, W; Taute, A; Roberson, A; Ofosu, ODate:Oct 2014Polyethylene was flame retarded with two intumescent-type additives, 3,5-diaminobenzoic acid phosphate and ethylenediamine phosphate, which differ with respect to their decomposition onset temperatures, along with varying ratios of two grades ...Read more
Author:Focke, WW; Muiambo, H; Mhike, W; Kruger, HJ; Ofosu, ODate:Feb 2014The 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.% expandable graphite ...Read more
Author:Mngomezulu, ME; Luyt, AS; Mathew, Maya JDate:Dec 2017This work reports on the effect of expandable graphite (EG) on the morphology, thermal and dynamic mechanical properties of flame retardant poly(lactic acid) (PLA)/EG composites. The composites were prepared by melt-mixing and their structure, ...Read more
Author:Mngomezulu, ME; Luyt, AS; Chapple, Stephen A; John, Maya JDate:Jan 2018This work reports on the effect of commercial expandable graphite (EG) on the flammability and thermal decomposition properties of PLA-starch blend. The PLA-starch/EG composites were prepared by melt-mixing and their thermal stability, volatile ...Read more
