Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable

Polycarbonate plastic products give you a balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a rugged material. Even though it features exceptional impact-resistance, it possesses reduced scratch-resistance and thus a hard coating typically is applied to polycarbonate eye protection lenses and polycarbonate exterior vehicle components. The properties relating to polycarbonate are comparable to those of common Acrylic materials, except polycarbonate is going to be 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 approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without breaking. For this reason, it may be processed and formed   at room temperature using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends with 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 created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and cannot be bent unless it is heated.

The light weight of polycarbonate, as opposed to glass, has led to growth and development of electronic display screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many LCD screens, though CRT, plasma screen and other LCD technologies generally still 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, riot shields, instrument panels, and 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that begins 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 and become a very thick liquid. This liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
