Lexan Polycarbonate Sheet offering light weight and break resistance
Polycarbonate plastic products offer a great blend of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it has higher impact-resistance, it's got minimal scratch-resistance and so a hard coating is often applied to polycarbonate eye protection and polycarbonate exterior automobile components. The properties associated with polycarbonate are generally comparable to those of Acrylic PMMA materials, and yet polycarbonate is 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 different types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo massive shape changes without breaking. For that reason, it is sometimes processed and formed without needing to be heated using standard sheet metal techniques, which include forming bends with a brake. Even for 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 important, which cannot be made from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and can't be bent with out a heating process.
Polycarbonate is often used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Many different types of lenses are produced from 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 typically made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
