Depends on the plastic. Thin acrylics like plexiglass up to 3/16 can be
scored and popped like glass. Any thicker and you have a high
probability of the crack wandering. Polycarbonates like lexan have to be
sawn.

For acrylics I find that high angle alternate bevel top laminate blade
minimizes chipping. For polycarbonates a tripplechip non-ferrous blade
prevents melting better. FOr softer stuff like Starboard almost any
carbide blade will work as long as it has a lot of teeth.
