Lexan Polycarbonate Sheeting offering light weight and break resistance

Bayer Makrolon Polycarbonate materials offer a balance of useful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a high quality material. Whilst it offers high impact-resistance, it possesses a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automobile components. The properties associated with polycarbonate are similar to that of those of common Acrylic materials, except 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 has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without breaking or cracking. For that reason, it may be 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 crucial, which should not be created from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and can't be bent without heating.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant see through applications that would normally indicate the use of glass, but require much higher impact-resistance. Many kinds of lenses are created 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
