Bayer Makrolon Polycarbonate Sheet are clear and tough

Polycarbonate plastic products give you a unique balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Though it offers high impact-resistance, it has got a lower scratch-resistance and thus a hard coating could be applied to polycarbonate eye protection lenses as well as polycarbonate exterior motor vehicle equipment. The properties relating to polycarbonate are generally comparable to 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 most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Due to this fact, it could be processed and formed   at room temperature using sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are essential, which can't be crafted from sheet metal. Keep in mind 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, compared with glass, has led to continuing development of electronic display 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 generally still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other kinds of 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 goods are made of 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 maybe 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 begins 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. This 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.
