Polycarbonate materials offer a balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Though it features higher impact-resistance, it's got reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection and polycarbonate exterior auto equipment. The properties associated with polycarbonate are similar those of polymethyl methacrylate (PMMA, acrylic), and yet polycarbonate is undoubtedly 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 near 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) in order to make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without cracking. Subsequently, it can be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are essential, which can not be produced from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently utilized in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Many different types of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
