Lexan Polycarbonate Flat Sheet are clear and tough

Makrolon Polycarbonate materials give you a balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very durable material. Even though it offers exceptional impact-resistance, it has got a lower scratch-resistance and so a hard coating typically is applied to polycarbonate eye wear lenses as well as polycarbonate exterior automobile equipment. The characteristics of polycarbonate tend to be along the lines of those of Acrylic PMMA materials, and yet 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 several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), as a result it softens slowly 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 make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking. For that reason, it may be processed and formed   without needing to be heated using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which can not be created from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is commonly utilized in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Many different types of lenses are made of 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 made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
