Sheffield Plastics Polycarbonate Sheeting are clear and tough

Bayer Makrolon Polycarbonate materials have a great blend of useful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very tough material. Whilst it features tremendous impact-resistance, it has got lower scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior motor vehicle equipment. The characteristics of polycarbonate are similar to those of Acrylic PMMA materials, although polycarbonate definitely 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 kinds of glass.
Polycarbonate carries 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 must be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking. Subsequently, it can be processed and formed   at room temperature using standard sheet metal techniques, which include forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which should not be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent with out a heating process.

The light weight of polycarbonate, compared to glass, has led to advancement of electronic display screens that replace glass materials 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 generally still require glass for its higher melting temperature and the 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, riot shields, instrument panels, and common style blender jars. Many toys and hobby products are produced 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 either can be a coating (e.g. for improved abrasion resistance), or perhaps the 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 and become a very thick liquid. The liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
