Bayer Makrolon Polycarbonate Flat Sheet offering light weight and break resistance
Polycarbonate materials give you a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very tough material. Though it offers increased impact-resistance, it has lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eye protection as well as polycarbonate exterior automobile components. The characteristics relating to polycarbonate are generally similar to those of common Acrylic materials, and yet 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without cracking. Subsequently, it may be processed and formed without needing to be heated using sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which should not be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it's brittle and cannot be bent with out a heating process.
Polycarbonate is commonly found in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
