I have two sheets of Thermoflect material - the stuff used in ORs as part of rewarming systems post operatively. Has a blue side and a silver side - says "Do Not Use In MRI" on the silver side. Fairly light, flexible, and fabric-like. Was going to do something DIY-like with them like line a UQ with them and never got around to it. If you think you can use it, PM me and I'll mail them to you (CONUS only). First come, first served - I will close this thread when taken.
