Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength

Polycarbonate plastic products have a unique balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it features very high impact-resistance, it has got minimal scratch-resistance and so a hard coating typically is applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), except 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 kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. For this reason, it could be processed and formed   at room temperature using 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 crucial, which can't be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and can't be bent with out a heating process.

The light weight of polycarbonate, in contrast to glass, has led to development of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several 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 miscellaneous items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby items are produced 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 either can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer 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, these small pellets are heated until they melt and become a very thick liquid. This liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
