Lexan Polycarbonate Flat Sheet are clear and tough

Makrolon Polycarbonate materials give you a great blend of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very sturdy material. Though it features significant impact-resistance, it possesses lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior motor vehicle components. The characteristics of polycarbonate are generally comparable to those of polymethyl methacrylate (PMMA, acrylic), 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate has 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 make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking. Due to this fact, it is sometimes processed and formed   cold using sheet metal techniques, for example 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 necessary, which cannot be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and cannot be bent without heating.

The light weight of polycarbonate, in contrast to glass, has led to advancement of electronic touch screens that replace glass 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 which still do 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, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby goods 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 could be needed. This either 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 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. 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.
