Sheffield Plastics Polycarbonate Flat Sheet are clear and tough

Makrolon Polycarbonate materials offer a great blend of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very high quality material. Even though it offers increased impact-resistance, it has got a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear lenses as well as polycarbonate exterior motor vehicle equipment. The properties associated with polycarbonate are generally comparable to those of polymethyl methacrylate (PMMA, acrylic), 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. Because of that, it may be processed and formed   cold using standard sheet metal techniques, for example forming bends on a brake. Even for 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 required, which cannot be made from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent with out a heating process.

The light weight of polycarbonate, as opposed to glass, has led to continuing development of electronic touch screens that replace the traditional 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 do require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items created 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 manufactured 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 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 at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt. The melted liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to produce a finished product in less than a minute.
