Melt-extruded polypropylene resin containing 1% or 2% ceresine wax yielded thin films that had significantly increased dielectric breakdown strengths but with virtually identical bulk dielectric properties. Ceresine wax acts as a trapping centre for electrons and by minimizing ionization of host polypropylene molecules, dielectric breakdown strength is increased.
