Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable

Polycarbonate materials give you a balance of beneficial features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a high quality material. Although it has considerable impact-resistance, it possesses low scratch-resistance and so a hard coating could be applied to polycarbonate eye wear lenses as well as polycarbonate exterior vehicle equipment. The properties of polycarbonate tend to be along the lines of those of common Acrylic materials, although polycarbonate is definitely 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive shape changes without cracking. Due to this fact, it could be processed and formed   at room temperature using sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having 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 may not be produced from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and cannot be bent at room temperature.

The light weight of polycarbonate, compared with glass, has led to advancement of electronic view screens that replace glass materials 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 the ability to be etched in finer detail.
Other miscellaneous items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby items are constructed 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 either can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt. The melted liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
