Bayer Makrolon Polycarbonate Sheets are clear and tough

Polycarbonate products offer a great blend of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Even though it has higher impact-resistance, it has minimal scratch-resistance and thus a hard coating typically is applied to polycarbonate eyeglasses and polycarbonate exterior motor vehicle equipment. The properties relating to polycarbonate are like those of common Acrylic materials, and yet polycarbonate is going to be 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 kinds of glass.
Polycarbonate has 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 ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Therefore, for small changes in shape, it can be processed and formed   cold using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be produced from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and can't be bent at room temperature.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require much higher impact-resistance. Many kinds of lenses are produced from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
