Covestro Makrolon Polycarbonate Flat Sheet offer high impact strength

Bayer Makrolon Polycarbonate materials have a unique balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a long-lasting material. Although it features extraordinary impact-resistance, it has got a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses as well as polycarbonate exterior vehicle equipment. The properties associated with polycarbonate tend to be similar those of Acrylic PMMA materials, except polycarbonate is undoubtedly 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 about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Therefore, it is sometimes processed and formed   cold using standard sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are necessary, which can not be made from sheet metal. Keep in mind that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it is brittle and can't be bent at room temperature.
Polycarbonate is frequently found in eye protection, in addition to other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require greater impact-resistance. Many kinds 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 normally produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
