Covestro Makrolon Polycarbonate Sheets are clear and tough

Makrolon Polycarbonate products offer a great blend of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a tough material. Even though it has very high impact-resistance, it has got a lower scratch-resistance and thus a hard coating is often applied to polycarbonate eyewear lenses and polycarbonate exterior automobile equipment. The properties associated with polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), except 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 it has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Hence, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be created from sheet metal. Note that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it’s brittle and can’t be bent at room temperature.

The light weight of polycarbonate, compared to glass, has led to continuing development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies generally still require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and 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 subjected to weathering or UV-radiation, a special surface treatment maybe needed. This can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins 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. This liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
