Bayer Makrolon Polycarbonate materials give you a great blend of useful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very high quality material. Even though it has outstanding impact-resistance, it possesses reduced scratch-resistance and so a hard coating could be applied to polycarbonate eye wear lenses and polycarbonate exterior automobile equipment. The characteristics relating to polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), and yet polycarbonate is 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 carries 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 ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large shape changes without cracking. Therefore, 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 generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and cannot be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to development of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few LCD screens, though CRT, plasma screen and other LCD technologies which still do require glass for its higher melting temperature and the ability to be etched with finer detail.
Other types of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and blender jars. Many toys and hobby products 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 could be 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, the pelletized resin is heated until they melt. The melted liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
