Covestro Makrolon Polycarbonate Sheets offering light weight and break resistance

Polycarbonate materials offer a great blend of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it offers very high impact-resistance, it's got minimal scratch-resistance and so a hard coating could be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior vehicle equipment. The characteristics associated with polycarbonate are generally similar to those of common Acrylic materials, yet , polycarbonate is going to be 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 several types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. As a result, it may be processed and formed   cold using standard sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which can not be made from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.

The light weight of polycarbonate, as opposed 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 a few 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 types of items produced 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 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 is needed. This may be a coating (e.g. for improved abrasion resistance), or as 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 begin to melt. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
