Bayer Makrolon Polycarbonate Flat Sheet are clear and tough

Polycarbonate products give you a great blend of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a long-lasting material. Although it has outstanding impact-resistance, it has a lower scratch-resistance and so a hard coating is applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive components. The characteristics associated with polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), although 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 it has better light transmission characteristics than many different types 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 warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without cracking. As a result, for small changes in shape, it can be processed and formed   cold using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, unlike glass, has led to advancement of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and its ability to be etched in finer detail.
Other kinds of items manufactured from 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 items are made 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 maybe needed. This 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 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 liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product in less than a minute.
