Lexan Polycarbonate Sheets are clear and tough

Bayer Makrolon Polycarbonate products give you a balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a high quality material. Though it offers extraordinary impact-resistance, it possesses a lower scratch-resistance and so a hard coating is often applied to polycarbonate eye protection lenses and polycarbonate exterior automotive equipment. The properties associated with polycarbonate are generally like those of polymethyl methacrylate (PMMA, acrylic), yet , 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 has a glass transition temperature of approximately 150 °C (302 °F), therefore 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 reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without cracking. As a result, it could be processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. For even 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 cannot be crafted from sheet metal. Be aware that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent without heating.

The light weight of polycarbonate, unlike glass, has led to advancement of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items made 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 goods are made 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer 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. This liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to create a finished product in less than a minute.
