Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance

Polycarbonate products offer a unique balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very tough material. Even though it has tremendous impact-resistance, it has low scratch-resistance and thus a hard coating is applied to polycarbonate eye protection and polycarbonate exterior motor vehicle components. The characteristics associated with polycarbonate are generally like those of Acrylic PMMA materials, 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 has better light transmission characteristics than several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. Because of that, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are important, which can not be produced from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and can't be bent with out a heating process.

The light weight of polycarbonate, unlike glass, has led to advancement of electronic display screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as 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 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 goods 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 may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that at the beginning, 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 melt. The melted liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
