Polycarbonate products offer a great blend of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very tough material. Although it offers outstanding impact-resistance, it has lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive components. The properties of polycarbonate are generally comparable to those of Acrylic PMMA materials, except 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 several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), therefore 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 stress-free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. Therefore, it is sometimes processed and formed at room temperature 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 needed, which can not be produced from sheet metal. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent unless it is heated.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require greater 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 commonly fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
