Covestro Makrolon Polycarbonate Sheeting are clear and tough

Polycarbonate materials give you a balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a rugged material. Though it features extraordinary impact-resistance, it has reduced scratch-resistance and thus a hard coating is often applied to polycarbonate eyewear and polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate are comparable to those of Acrylic PMMA materials, but polycarbonate definitely is 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 has a glass transition temperature of around 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. For that reason, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even 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 needed, which should not be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent unless it is heated.

The light weight of polycarbonate, compared with glass, has led to growth and development of electronic touch 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 generally still require glass for its higher melting temperature and its 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 common style blender jars. Many toys and hobby products are made 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 is needed. This may 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, the pellets are heated until they melt and become a very thick liquid. The melted liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product in a matter of minutes.
