Sheffield Plastics Polycarbonate Sheets are clear and tough

Makrolon Polycarbonate products give you a balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very tough material. Although it offers greater impact-resistance, it has got lower scratch-resistance and so a hard coating could be applied to polycarbonate eye wear and polycarbonate exterior vehicle components. The characteristics of polycarbonate are generally similar those of polymethyl methacrylate (PMMA, acrylic), yet , polycarbonate is undoubtedly 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), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without cracking or breaking. As a result, it may be processed and formed   cold using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are essential, which can not be produced from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and can't be bent without heating.

The light weight of polycarbonate, compared to glass, has led to growth and development of electronic display screens that replace the traditional 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 generally still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other miscellaneous items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby goods 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 could be 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 at the beginning, 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 and become a very thick liquid. This 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 create a finished product , that only takes about a minute to complete.
