Abstract: The present disclosure relates to masterbatch compositions comprising a base polymer and carbon black and carbon nanotubes as filler that can be used to prepare an article with improved electrical or mechanical performance relative to a masterbatch having carbon black filler alone. The masterbatch compositions can also be used to prepared colored articles without sacrificing electrical or mechanical performance as is typically seen with highly-loaded carbon black-filled compositions.
