I've routed several kinds - up to 3/4" router bits - full speed.
"Lexan" - produced long spider-web strings
Acrylic - routs well
UHMWPE - difficult but doable. Must push/move hard against the bit - almost to the point where you think you will break the bit! Not surprising - the stuff is designed to reduce friction.
* Always on a router table
* Always small cuts (1/8") at a time
* Always keep the plastic moving to avoid melting
