Bayer Makrolon Polycarbonate Sheets are clear and tough

Polycarbonate materials have a great blend of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very rugged material. Although it offers exceptional impact-resistance, it's got low scratch-resistance and so a hard coating is applied to polycarbonate eye wear and polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate tend to be 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently 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 make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. Therefore, it may be processed and formed   at room temperature using standard sheet metal techniques, for example forming bends with 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 required, which should not be crafted from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent at room temperature.
Polycarbonate is frequently utilized in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally require the use of glass, but require higher impact-resistance. Several 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
