Covestro Makrolon Polycarbonate Sheeting are clear and tough

Bayer Makrolon Polycarbonate materials offer a unique balance of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a tough material. Whilst it features tremendous impact-resistance, it possesses a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear and polycarbonate exterior vehicle components. The characteristics of polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is definitely 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), in order that 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) to help make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. Hence, it may be processed and formed   without needing to be heated using sheet metal techniques, for example forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which cannot be made from sheet metal. Understand that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, compared to glass, has led to development of electronic view screens that replace glass materials 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 kinds of items produced from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby products are made out of 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 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 begins 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 melted liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
