Bayer Makrolon Polycarbonate Flat Sheet offering light weight and break resistance

Bayer Makrolon Polycarbonate products have a balance of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a rugged material. Though it has tremendous impact-resistance, it has got low scratch-resistance and so a hard coating typically is applied to polycarbonate eyewear and polycarbonate exterior auto equipment. The properties associated with polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate is definitely 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 carries a glass transition temperature of about 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Due to this fact, for small changes in shape, it can be processed and formed   at room temperature using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are important, which should not be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent unless it is heated.
Polycarbonate is often used in eye protection, along with other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Many different types of lenses are made of 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 typically made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
