Lexan Polycarbonate Sheet offering light weight and break resistance
Bayer Makrolon Polycarbonate materials have a unique balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it offers outstanding impact-resistance, it's got a lower scratch-resistance and so a hard coating may be applied to polycarbonate eye protection and polycarbonate exterior auto components. The characteristics associated with polycarbonate are comparable to those of Acrylic PMMA materials, and yet polycarbonate is going to be 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), therefore 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) for making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking. For that reason, it may be processed and formed cold using standard sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which cannot be created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent with out a heating process.
Polycarbonate is often used in eye protection, as well as in other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require much 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 commonly fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
