Microwave extraction works for me for most solid matrices, never tried plastics but if you don't raise too much the temperature it should work i guess.
Diethyl ether should be capable to capture microwaves since it is enough polar, if it doesn't you could add silicon carbide (they sell those) in the vessels.
If you want to be sure that the PTFE vessels are free from phthalates you can use a microwave that allows glass insert like mine.
They are used for one extraction then discarded, no contamination, no carryover (like with ASE), less costs, less solvent consumption than sohxlet, very good recoveries.
It doesn't like high metal content though.
