They used to make a heat moldable acrylic in Germany called rohadur. It was a clear reddish plastic, the cat's ass for making orthotics, best stuff ever, easy to handle, heat mold numerous times and it would not get brittle, or really change at all. Had the perfect characteristics for an orthotic, firm, but not too hard, could be made thin so it would fit in your Ferragamo loafers, or whatever. They quit making it. Turns out the guys working in the factory where they made it were turning up with liver cancer. It was some sort of methyl methacrylate. If you have ever worked with it, you know is moderately nasty smelling stuff, and you don't want to get any on you. I have used it where I put the suction right over it while mixing it, the newer kits seal.
How did the old glue smell?
