Sheffield Plastics Polycarbonate Flat Sheet offer high impact strength

Makrolon Polycarbonate products give you a unique balance of useful 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 rugged material. Although it features exceptional impact-resistance, it possesses lower scratch-resistance and thus a hard coating is applied to polycarbonate eye wear as well as polycarbonate exterior auto equipment. The properties of polycarbonate are generally similar to that of those of Acrylic PMMA materials, yet , 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens slowly 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) in order to make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without cracking. Therefore, it can be processed and formed   cold using sheet metal techniques, such as 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 essential, which can't be created from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.

The light weight of polycarbonate, compared to 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 some LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of 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 constructed 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 could be needed. This either can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer 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, this pellet material is 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 produce a finished product , all in just a minute or so.
