Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength

Makrolon Polycarbonate materials give you a unique balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very rugged material. Though it has greater impact-resistance, it has low scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses and polycarbonate exterior automobile components. The properties associated with polycarbonate are generally similar those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate definitely 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), so 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 stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large changes in basic shape without 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 having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which can't be produced from sheet metal. Understand that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is frequently 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 higher 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
