Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance

Polycarbonate products offer a balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a tough material. Though it offers considerable impact-resistance, it's got minimal scratch-resistance and so a hard coating is applied to polycarbonate eye protection lenses and polycarbonate exterior automobile components. The characteristics of polycarbonate tend to be comparable to those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate is actually 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 has a glass transition temperature of around 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. For this reason, it can be processed and formed   at room temperature using sheet metal techniques, which include forming bends on a brake. Even for 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 cannot be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it is brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, in contrast to glass, has led to advancement of electronic view 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 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 blender jars. Many toys and hobby goods are made 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 may 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, the pellets are heated until they begin to melt. The liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
