Covestro Makrolon Polycarbonate Sheet are clear and tough

Bayer Makrolon Polycarbonate materials have a balance of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very durable material. Although it features tremendous impact-resistance, it possesses minimal scratch-resistance and so a hard coating is applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior automobile components. The properties associated with polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), and 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 has better light transmission characteristics than several 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 must be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without breaking. Therefore, it is sometimes processed and formed   cold using sheet metal techniques, which include forming bends with a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, as opposed to glass, has led to development of electronic display screens that replace glass materials 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 the ability to be etched with finer detail.
Other miscellaneous 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 goods 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 could be needed. This either can be a coating (e.g. for improved abrasion resistance), or 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 melt in to a thick liquid. This liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
