Anyway, I do know that they make plastics and polymers like the kind Mark
mentions where you either have to superheat and mold them with a vacuum
device or apply a hardener resin. However, the last time I got a PET (Photo
Emission Topography) scan a few years back, they secured my head to the
headrest with a sheet of thermoplastic that was much easier to use (it
seemed). Basically, it was a 1/16" thick sheet of semi-flexible plastic,
approximately 10" (width) x 30" (length), and it had eye/nose/mouth holes
cut out of it. They dipped this sheet in boiling water and formed it around
my face and it hardened very fast (possibly less than a minute). This post
heating hardened state was much more rigid than when it was applied to my
face, but I'm not sure of the material's rigidity in it's original state.
The material is called Kydex, and seems to come in 20x22" sheets, or
thereabouts. I'm not sure where to get them, but I haven't done lots
of research recently; if anyone finds a supplier of such sheets,
please let me know.
(Very small strips, about 1x3", are sold by one of the local crafts
stores around Cambridge MA under the name of "Friendly Plastic".)
