Bayer Makrolon Polycarbonate Flat Sheet are clear and tough

Polycarbonate plastic products have a balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very tough material. Whilst it has significant impact-resistance, it has reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior vehicle equipment. The properties associated with polycarbonate tend to be comparable to those of Acrylic PMMA materials, although polycarbonate is definitely 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), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without cracking. For that reason, for small changes in shape, it can be processed and formed   at room temperature using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends with 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 made from sheet metal. Remember that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is frequently found in eye protection, along with other projectile-resistant see through applications that would normally require the use of glass, but require greater impact-resistance. Many different types of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.

Lexan Polycarbonate Flat Sheet are considered unbreakable

Bayer Makrolon Polycarbonate products give you a great blend of useful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is a very rugged material. Though it has outstanding impact-resistance, it has lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are generally comparable to those of common Acrylic materials, except polycarbonate 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 most grades of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. As a result, for small changes in shape, it can be processed and formed   cold using standard sheet metal techniques, for example forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which cannot be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and cannot be bent without heating.

The light weight of polycarbonate, compared with glass, has led to development of electronic touch screens that replace 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 which still require glass for its higher melting temperature and its ability to be etched in finer detail.
Other miscellaneous items manufactured 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 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 maybe needed. This may 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 begin to melt. This liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
