Sheffield Plastics Polycarbonate Sheeting are clear and tough

Bayer Makrolon Polycarbonate products give you a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a tough material. Although it offers high impact-resistance, it's got a lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eyewear as well as polycarbonate exterior motor vehicle equipment. The characteristics of polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), except 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 many kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. Therefore, it may be processed and formed   at room temperature using sheet metal techniques, for example forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are essential, which can't be created from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, compared to glass, has led to growth and development of electronic display screens that replace the traditional glass 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 which still do require glass for its higher melting temperature and the ability to be etched in finer detail.
Other miscellaneous items made out of 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 made 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 maybe 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 plastic material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt. This liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
