Mark: You should check-out the web-site - www.krempel.com. This is a German company and has FR-4 material that can be used for bend application. Typically, you can get FR-4 as thin as 0.0016", but you need to use traditional coverlay as a coating for it to be able to bend without cracking. I am not sure of the bend radius, but folks at Krempel may be able to help.
