Covestro Makrolon Polycarbonate Flat Sheet offering light weight and break resistance

Polycarbonate materials offer a unique balance of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very tough material. Though it offers extraordinary impact-resistance, it has got low scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses and polycarbonate exterior auto components. The properties associated with polycarbonate tend to be comparable to those of polymethyl methacrylate (PMMA, acrylic), yet , polycarbonate is undoubtedly 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 different types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Due to this fact, it is sometimes processed and formed   cold using standard sheet metal techniques, for example forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which can not be made from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent unless it is heated.

The light weight of polycarbonate, in contrast to glass, has led to advancement of electronic display screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many 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 kinds of items manufactured 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 goods 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 may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that 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 injected into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
