Bayer Makrolon Polycarbonate Sheet are clear and tough
Makrolon Polycarbonate materials give you a unique balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a long-lasting material. Although it offers tremendous impact-resistance, it has reduced scratch-resistance and so a hard coating can be applied to polycarbonate eyewear lenses and polycarbonate exterior automobile equipment. The characteristics relating to polycarbonate are similar to that of those of Acrylic PMMA materials, but 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without cracking or breaking. Because of this, it is sometimes processed and formed  cold using standard sheet metal techniques, for example forming bends with a brake. For even 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 needed, which should not be made from sheet metal. Be aware that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent without heating.
The light weight of polycarbonate, in contrast to glass, has led to development of electronic view screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other miscellaneous items produced 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 products are produced 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 is 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 begins 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 and become a very thick liquid. The melted liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
