Polycarbonate plastic products give you a balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very rugged material. Even though it features higher impact-resistance, it has reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior motor vehicle components. The characteristics associated with polycarbonate are generally like 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 of about 150 °C (302 °F), consequently it softens slowly 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) to help with making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. Because of this, it may be processed and formed cold using sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can't be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently found in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require higher impact-resistance. Many kinds of lenses are created from 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 typically made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
