This will work also. Set the saw to a little less than half the thickness
of the plastic and slice a kerf on each side. Now snap it. You will have a
little edge in the center that is easy to file, sand or scrape.
This should give you a nice sharp edge.
While cutting use a steady feed rate. Slowing down and stopping will scorch
the edge. Usually blades used for plastic have no set to the teeth on the
blade.

they come up with this striped stuff.
