Polycarbonate products offer a unique balance of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very high quality material. Even though it has tremendous impact-resistance, it has got a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection and polycarbonate exterior automotive equipment. The characteristics relating to polycarbonate are generally like 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 has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without breaking. For this reason, it can be processed and formed cold using standard sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can't be created from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and can't be bent at room temperature.
Polycarbonate is commonly used in eye protection, and also in other projectile-resistant see through applications that would normally require the use of glass, but require much greater impact-resistance. Several types of lenses are manufactured 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 typically made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
