10 - </b>Some of our robots use Polycarbonate. Why, because it is very strong. The image to the right is of me trying really hard to bend one of the
11 - H2 bottom panels. It really hurt holding this long enough&nbsp; for the camera to snap the image. When I let go it returned to its normal flat
12 - shape, no worse for the wear. Now Polycarbonate is not indestructible, but it is very tough. A 1/8" thick x 1/4" wide strip can be

128 - Lexan is the same material used in bullet proof glass. It is very strong, but has one important weakness. In the presence of certain chemicals,
129 - it will "craze". This means it will crystallize, become brittle, and even shatter. One substance in particular to watch out for is 1,
130 - 1, 1 Trichloroethane. This is a solvent, present in some motor cleaners and degreasers, which will crystallize polycarbonate on contact.
131 - Trichloroethane is a liquid CFC and has been removed from use, but may still be out there. Some products have switched to its cousin, 1, 1,
132 - Difluoroethane. While not as vigorously reactive as the previous chemical, it is still capable of crazing Lexan if allowed to come into contact
