Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable

Polycarbonate materials offer a great blend of helpful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a tough material. Although it offers outstanding impact-resistance, it has a lower scratch-resistance and so a hard coating could be applied to polycarbonate eyewear lenses and polycarbonate exterior auto components. The characteristics of polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), and yet polycarbonate is 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 most grades of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking or cracking. Therefore, for small changes in shape, it can be processed and formed   at room temperature using standard sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can not be made from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, in contrast to glass, has led to development of electronic display screens that replace the traditional 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 with finer detail.
Other types of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby goods are produced from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment is needed. This either can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The 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 pellets are heated until they begin to melt. This liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
