Sheffield Plastics Polycarbonate Sheets offer high impact strength

Bayer Makrolon Polycarbonate materials give you a great blend of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very durable material. Though it offers significant impact-resistance, it has got lower scratch-resistance and so a hard coating could be applied to polycarbonate eye protection as well as polycarbonate exterior automotive components. The properties relating to polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), but 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 several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking. Because of this, it may be processed and formed   at room temperature using 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 required, which can not be produced from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, compared to glass, has led to development of electronic display screens that replace 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 still generally require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby items are made of 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 can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that 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 in to a thick liquid. This 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 create a finished product in less than a minute.
