Lexan Polycarbonate Flat Sheet offer high impact strength

Polycarbonate products offer a balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a rugged material. Though it offers significant impact-resistance, it has a lower scratch-resistance and thus a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior motor vehicle components. The characteristics of polycarbonate tend to be similar to those of Acrylic PMMA materials, but polycarbonate definitely 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at 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. Due to this fact, for small changes in shape, it can be processed and formed   without needing to be heated using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which should not be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be 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 touch 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 still generally require glass for its higher melting temperature and its ability to be etched with finer detail.
Other kinds of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby products 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 may be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer 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 pelletized resin is heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
