Polymer–carbon nanotube composites for flame-retardant cable applications
G. Beyer, Kabelwerk Eupen AG, Belgium
Abstract:
This chapter describes multi-walled carbon nanotubes (MWCNTs) as very efficient flame retardants at low filler contents in ethylene vinyl acetate (EVA). An optimized formulation for flame-retardant insulated wires was developed based on the filler-blend ‘multi-walled carbon nanotubes–organoclays–aluminium trihydrate’. The char was improved and strengthened by the long length/diameter ratio of the MWCNTs, resulting in better flameretardant performances of the wires.
