Lexan Polycarbonate Flat Sheet offering light weight and break resistance

Polycarbonate products offer a unique balance of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very long-lasting material. Even though it has very high impact-resistance, it has got reduced scratch-resistance and so a hard coating may be applied to polycarbonate eyewear lenses as well as polycarbonate exterior automotive components. The characteristics relating to polycarbonate are generally along the lines of those of Acrylic PMMA materials, and yet 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 carries a glass transition temperature near 150 °C (302 °F), in order that it softens slowly 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) to help with making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without breaking. For this reason, it may be processed and formed   cold using standard sheet metal techniques, for instance forming bends on a brake. For even 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 required, which can not be made from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and cannot be bent at room temperature.

The light weight of polycarbonate, compared to glass, has led to growth and development of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as 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 with finer detail.
Other types of items made from 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 goods are produced 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt in to a thick liquid. The melted liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
