Sheffield Plastics Polycarbonate Sheet are clear and tough

Bayer Makrolon Polycarbonate products have a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a high quality material. Though it offers greater impact-resistance, it possesses low scratch-resistance and so a hard coating is applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are generally along the lines of those of common Acrylic materials, yet , polycarbonate is 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 many different types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Because of that, it could be processed and formed   cold using standard sheet metal techniques, for example forming bends with a brake. Even for 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 required, which can not be made from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.

The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic touch screens that replace 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 still generally require glass for its higher melting temperature and its ability to be etched with 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 products are manufactured from 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 may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer 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, these small pellets are heated until they melt. This liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
