Covestro Makrolon Polycarbonate Sheet are clear and tough

Makrolon Polycarbonate materials give you a balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a tough material. Whilst it features extraordinary impact-resistance, it possesses a lower scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses lenses and polycarbonate exterior vehicle components. The characteristics associated with polycarbonate are along the lines of those of polymethyl methacrylate (PMMA, acrylic), but 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 carries a glass transition temperature near 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo large deformations without breaking. Due to this fact, it could be processed and formed   without needing to be heated using sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which can not be produced from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and can't be bent without heating.

The light weight of polycarbonate, compared to glass, has led to development of electronic touch screens that replace the traditional 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 which still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other miscellaneous items manufactured 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 products are constructed from 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 maybe needed. This either can be a coating (e.g. for improved abrasion resistance), or as a 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, 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 produce a finished product , that only takes about a minute to complete.
