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 definitely a long-lasting material. Though it offers high impact-resistance, it's got low scratch-resistance and thus a hard coating typically is applied to polycarbonate eyeglasses and polycarbonate exterior motor vehicle equipment. The characteristics associated with polycarbonate are generally like those of common Acrylic materials, and yet polycarbonate is always 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 most grades of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), therefore 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 make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Hence, it can be processed and formed   at room temperature using standard sheet metal techniques, which include forming bends with 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 important, which can not be created from sheet metal. Please keep in mind 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, compared with glass, has led to continuing development of electronic display screens that replace glass materials 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 which still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other kinds of items created 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 items are constructed 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 is needed. This either can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, these small pellets are heated until they melt in to a thick liquid. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to form a finished product in less than a minute.
