David, I have experimented with some simple ducting for my Limulus system. I found a Vinyl Flashing from Union Corrugating Company (purchased at Lowes home center) that has some nice features, it is bendable, holds its shape, easy to cut, and has a low carbon content (harder to burn than most plastics), and it is fairly stiff.
My needs are "low temp" air ducting. I have not tested it with constant warm/hot air. -- Doug > Anybody know of a nice cheap, high melting point, easy to work with > sheet material, for making a custom air shroud? > > We have one box with stuff in it that looks similar to HDPE, the > material the white flexible cutting boards are made of, but it is a bit > thinner and more rigid that that.
