type of filament to withstand high voltage and temperature

I have a bug zapper that had the electrode separators fail.I designed a new electrode separator out of ABS which also failed. The ABS started tracking between the electrodes and then failed/melted. Is there a plastic that can with stand voltage between 2,000 and 4,000 volts and also withstand high temperature? Thanks, Gary

Perhaps the black colour contains carbon?

Tried PETG?

This is one occasion I would not try to use 3D printing.  Or at least not FDM.  In outdoor exposure, moisture will collect in the space between the strands of filament and at those voltages will allow current to leak between the terminals.  You could try sealing with an epoxy or similar but I wouldn't trust it.  I was a high voltage power lineman for decades and have tested thousands of 'hot sticks' over the years.  It takes very little moisture to cause problems.  In the US electric utilities are required to test their insulated tools for leakage current annually.

 Hi richnormand

 I thank you about your suggestion that its possible that there is  carbon in the black filament, you are right, I switched to prusament PC Orange and the Bug Zapper has been working  for five days without any indications of shorting across the plastic. Thanks, again for your help, Gary
