The breadboard material of choice for HV is HDPE- High Density PolyEthylene
(aka the white plastic cutting board from the local discount store).. Cheap,
easy to machine, good HV properties.  Plexiglas (a tradename for acrylic) is
brittle and tends to crack when machined, and gets worse with ozone/UV.  If
you want clear plastic use a polycarbonate (e.g. Lexan) that has been UV
inhibited (most of the "window glazing" stuff is inhibited).
