Sheffield Plastics Polycarbonate Sheeting are considered unbreakable

Polycarbonate plastic materials give you a balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is a very high quality material. Even though it features high impact-resistance, it's got a lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eyewear lenses and polycarbonate exterior automobile components. The characteristics of polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate is going to be 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 carries 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 should be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without breaking. Subsequently, it could be processed and formed   at room temperature using standard sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which may not be created from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.

The light weight of polycarbonate, compared with glass, has led to continuing development of electronic display screens that replace glass 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 still generally require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items produced from 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 products 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they begin to melt. The liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product in less than a minute.
