Bayer Makrolon Polycarbonate Sheets are clear and tough
Polycarbonate plastic products give you a great blend of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Although it offers higher impact-resistance, it has reduced scratch-resistance and thus a hard coating could be applied to polycarbonate eyewear as well as polycarbonate exterior vehicle equipment. The properties relating to polycarbonate tend to be similar to that of those of Acrylic PMMA materials, except 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. For that reason, it may be processed and formed cold using sheet metal techniques, such as forming bends on a brake. For even 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 needed, which may not be produced from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can't be bent without heating.
Polycarbonate is often found in eye protection, along with other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require greater impact-resistance. Several types of lenses are produced from 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 commonly made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
