Bayer Makrolon Polycarbonate Sheet are clear and tough

Makrolon Polycarbonate materials give you a great blend of useful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a sturdy material. Though it offers significant impact-resistance, it has minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye wear and polycarbonate exterior vehicle equipment. The characteristics associated with polycarbonate are generally similar to those of Acrylic PMMA materials, but polycarbonate is actually 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 many kinds of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), therefore 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 make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without cracking or breaking. For this reason, it may be processed and formed   at room temperature using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which can not be produced from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and can't be bent with out a heating process.

The light weight of polycarbonate, as opposed to glass, has led to development of electronic view 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 still generally 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, police 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 is needed. This may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The 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 pellets are heated until they begin to melt. This 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 in less than a minute.
