Lexan Polycarbonate Sheets offer high impact strength

Polycarbonate products offer a balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a rugged material. Whilst it has extraordinary impact-resistance, it has low scratch-resistance and so a hard coating may be applied to polycarbonate eyewear lenses and polycarbonate exterior motor vehicle components. The properties of polycarbonate are generally similar to those of common Acrylic materials, although 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 many different types of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at high temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. As a result, it can be processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends with a brake. Even for 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 required, which may not be produced from sheet metal. Understand that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is often used in eye protection, in addition to other projectile-resistant see through applications that would normally indicate the use of glass, but require much higher 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
