Covestro Makrolon Polycarbonate Flat Sheet are considered unbreakable

Polycarbonate plastic products offer a unique balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it features very high impact-resistance, it has a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior auto components. The properties associated with polycarbonate are generally similar those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate is undoubtedly 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 several types of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic deformations without breaking. Subsequently, it may be processed and formed   cold using standard sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which may not be created from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and can't be bent unless it is heated.

The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic display screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several 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 with finer detail.
Other miscellaneous items manufactured 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 items are manufactured 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 as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they begin to melt. This liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to create a finished product in a matter of minutes.
