Polycarbonate plastic products offer a great blend of useful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very high quality material. Although it has higher impact-resistance, it possesses low scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses and polycarbonate exterior automotive components. The characteristics of polycarbonate are similar those of Acrylic PMMA 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 several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), consequently 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) to help make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. As a result, it is sometimes processed and formed without needing to be heated using standard sheet metal techniques, such as forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which can't be crafted from sheet metal. Understand that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it's brittle and cannot be bent at room temperature.
Polycarbonate is frequently 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 higher impact-resistance. Many different types of lenses are made of 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 normally made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
