You might try DMAC with 3% LiCl. Polyimide films are normally cast from the polyamic acid which is then cured and is insoluble. The powder can also be sintered into a film but may not be clear. Frank
I think RTP's grades are thermoplatics.
Any idea for processing PI thermosert powder for films ?
I would rather use wet dipping or wet spinning, but how to dissolve the powder ?

Is there an extruderable grade of polyimide?
