Lexan Polycarbonate Sheeting offering light weight and break resistance

Bayer Makrolon Polycarbonate products offer a great blend of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Whilst it offers exceptional impact-resistance, it possesses a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses as well as polycarbonate exterior motor vehicle equipment. The properties relating to polycarbonate are similar to that of those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate is definitely 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 most grades of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without cracking or breaking. Due to this fact, it may be processed and formed   without needing to be heated using sheet metal techniques, which include 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 essential, which cannot be made from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in looks 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 continuing development of electronic display screens that replace 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 its ability to be etched with finer detail.
Other miscellaneous items created 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 products are made out 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or perhaps the 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, the pelletized resin is heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
