I think burring tool tips will clog with most plastics as you rightly say due to the fact that the chip does not break. However with some high impact plastics which are quite brittle it may just work. The trouble is that the heat generated with machining softens the plastic and the chip stops breaking again. Maybe a good supply of coolant will help?

At the end of the day you can but try.

These are a couple of good tool suppliers that may be worth a call for the tips you are after:
