Covestro Makrolon Polycarbonate Flat Sheet are considered unbreakable

Makrolon Polycarbonate products offer a unique balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very tough material. Though it features high impact-resistance, it possesses a lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eye wear lenses and polycarbonate exterior automotive equipment. The characteristics relating to polycarbonate are generally comparable to those of common Acrylic materials, except 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 most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Hence, for small changes in shape, it can be processed and formed   cold using sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which should not be made from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent unless it is heated.

The light weight of polycarbonate, unlike glass, has led to continuing 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 its ability to be etched in finer detail.
Other miscellaneous items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police 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 either 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, these small pellets are heated until they melt in to a thick liquid. The melted liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
