Covestro Makrolon Polycarbonate Flat Sheet are clear and tough

Polycarbonate plastic materials give you a great blend of beneficial features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Whilst it has exceptional impact-resistance, it has low scratch-resistance and so a hard coating is applied to polycarbonate eyewear as well as polycarbonate exterior automobile equipment. The properties of polycarbonate are comparable to those of common Acrylic materials, although 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 many different types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. Hence, it is sometimes processed and formed   at room temperature using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are important, which can not be created from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it's brittle and cannot be bent at room temperature.

The light weight of polycarbonate, unlike glass, has led to growth and development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several 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 kinds of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby items are produced 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 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 at the beginning, 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. The melted liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
