Lexan Polycarbonate Sheets are considered unbreakable

Polycarbonate plastic products have a great blend of beneficial features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is a very durable material. Whilst it offers outstanding impact-resistance, it possesses low scratch-resistance and thus a hard coating typically is applied to polycarbonate eye wear and polycarbonate exterior auto equipment. The characteristics of polycarbonate tend to be similar to that of those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is actually stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo large changes in basic shape without cracking. Because of that, for small changes in shape, it can be processed and formed   cold using standard sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which may not be created from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.

The light weight of polycarbonate, as opposed to glass, has led to continuing development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and the ability to be etched in finer detail.
Other miscellaneous items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby goods are constructed from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications subjected to weathering or UV-radiation, a special surface treatment maybe needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
