Lexan Polycarbonate Flat Sheet are clear and tough
Polycarbonate plastic materials give you a balance of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very tough material. Even though it has greater impact-resistance, it has got low scratch-resistance and thus a hard coating is applied to polycarbonate eye wear lenses and polycarbonate exterior motor vehicle components. The properties associated with polycarbonate are generally similar those of common Acrylic materials, yet , polycarbonate is actually 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 has a glass transition temperature near 150 °C (302 °F), as a result it softens gradually 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) in order to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking. Because of that, it could be processed and formed cold using standard sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which may not be made from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent with out a heating process.
Polycarbonate is frequently found in eye protection, along with other projectile-resistant viewing and lighting applications that would normally require 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
