Covestro Makrolon Polycarbonate Flat Sheet are clear and tough

Polycarbonate plastic products offer a unique balance of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very high quality material. Although it offers extraordinary impact-resistance, it has minimal scratch-resistance and thus a hard coating typically is applied to polycarbonate eye wear lenses and polycarbonate exterior automotive components. The characteristics associated with polycarbonate are like those of Acrylic PMMA materials, but polycarbonate is always 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 most grades of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. For this reason, it could be processed and formed   at room temperature using standard sheet metal techniques, for instance 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 may not be produced from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent with out a heating process.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally require the use of glass, but require greater 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
