Sheffield Plastics Polycarbonate Sheets are considered unbreakable
Bayer Makrolon Polycarbonate products offer a balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a rugged material. Though it has tremendous impact-resistance, it has got minimal scratch-resistance and thus a hard coating typically is applied to polycarbonate eyewear lenses and polycarbonate exterior vehicle equipment. The characteristics of polycarbonate are similar to that of those of common Acrylic materials, 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 several types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens slowly 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 help with making strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. Because of that, it is sometimes processed and formed  cold 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 necessary, which can not be crafted from sheet metal. Understand that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is frequently utilized in eye protection, in addition to other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
