Sheffield Plastics Polycarbonate Flat Sheet offer high impact strength

Bayer Makrolon Polycarbonate materials give you a unique balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a high quality material. Though it has outstanding impact-resistance, it's got low scratch-resistance and thus a hard coating is applied to polycarbonate eyewear and polycarbonate exterior automobile equipment. The properties relating to polycarbonate tend to be along the lines of those of common Acrylic materials, although 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 most grades 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 are required to be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. For that reason, it could be 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 useful for prototyping applications where transparent or electrically non-conductive parts are needed, which can't be made from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent without heating.
Polycarbonate is frequently used in eye protection, and also in other projectile-resistant viewing and lighting 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
