The few pieces I found in my garage are all rated for 90 degree C conductors max.
I don't think it's that simple.
Unless marked for a higher temp it is limited to 75? with an ambient less than 50? c unless it's in a concrete outside trench theit's good for 90?.
That said, you can, of course, use 90? wire, just limted to the 75? ampacity.

Here's some info from Carlon. Their conduit is rated for 90 degree C conductors.
