Lexan Polycarbonate Sheeting offer high impact strength

Bayer Makrolon Polycarbonate materials have a balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Though it offers extraordinary impact-resistance, it possesses lower scratch-resistance and so a hard coating could be applied to polycarbonate eye protection as well as polycarbonate exterior automotive components. The properties of polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), except 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 has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), so it softens gradually 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) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without breaking. Hence, it is sometimes processed and formed   cold using sheet metal techniques, for example forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be created from sheet metal. Note that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Several types 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 typically crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
