There's been a lot of talk about insultex and a similar foam used in packing. I haven't seen either of these things with my own eyes, but we have a lot of this stuff at work used in packing (see pics hopefully below). It's like a closed cell foam about 1/8" (.35mm) thick. It seems to me it could at a pinch work as a light pad. Does anyone know what it is and has anyone ever used it?
