We have used both black delrin and black (smoked color) acrylic with 
no HV leakage or tracking.

When you tap the acrylic for the fasteners be sure to use kerosine if 
in a lathe.  Also gently (very gently) anneal the acyrlic after 
tapping in your oven to prevent the sharp tap edge points from 
expanding into cracks that will radiate to the edge of the acrylic 
and cause fastener failure.
