Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable
Makrolon Polycarbonate materials offer a unique balance of useful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very high quality material. Although it has increased impact-resistance, it has got minimal scratch-resistance and thus a hard coating may be applied to polycarbonate eye wear lenses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate tend to be similar those of Acrylic PMMA materials, and yet polycarbonate is always 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 has a glass transition temperature of approximately 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo large changes in basic shape without cracking or breaking. Therefore, for small changes in shape, it can be processed and formed  cold using standard sheet metal techniques, for instance forming bends on a brake. For even 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 crucial, which should not be made from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent without heating.
The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic touch screens that replace glass 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 which still require glass for its higher melting temperature and its ability to be etched with finer detail.
Other kinds of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby items are made 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 is needed. This 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, the pellets are heated until they melt. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
