Similar (less expensive) materials to UHMW plastic
(OP)
We use some 18" diameter x 1/2" width UHMW plastic plates as lightweight training plates for weightlifting. They're insanely strong, but the ones we got aren't available anymore. We'd like to have some new ones made, but need something strong, yet not quite as expensive as UHMW.
Any suggestions as to what we should be looking at? We were quoted almost $100 per plate, which isn't going to happen, we were thinking on the order of $25 would be ideal, cheaper if possible and bought in bulk.

OR, call your local plastic supplier, and ask him to suggest a material that would be cheap in 1/2" plate form.
OR, with a modest tooling charge, you could get the plates cast from polyurethane. This also presents an opportunity, in that the plates can be cast to finished size, and can have markings, e.g. "Property of ____" cast in.

I got a quote for around $47 for UHMW and $38 for HDPE. The info on broad general types of plastics I just can't find anywhere easily accessible.

Yes, your plate will end up slightly under 18" diameter when you turn a plate of this size into four smaller ones. That may not matter to you, or it may be a deal breaker.
McMaster-Carr is probably not going to be your lowest cost option for material so you should be able to find a better price elsewhere.

Not sure if they'll sell a single sheet but worth a try.
