Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable

Makrolon Polycarbonate products offer a balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a long-lasting material. Though it has high impact-resistance, it has got a lower scratch-resistance and so a hard coating is applied to polycarbonate eye protection lenses and polycarbonate exterior motor vehicle components. The characteristics relating to polycarbonate are similar to that of those of Acrylic PMMA materials, 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 different types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo massive shape changes without breaking. Therefore, it is sometimes processed and formed   without needing to be heated 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 valuable in prototyping applications where transparent or electrically non-conductive parts are important, which should not be created from sheet metal. Remember that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is commonly found in eye protection, in addition to other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Many different types of lenses are manufactured 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 commonly crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
