Polycarbonate plastic products give you a unique balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Although it has higher impact-resistance, it has got minimal scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses and polycarbonate exterior auto components. The properties relating to polycarbonate are generally similar those of Acrylic PMMA materials, except polycarbonate is going to be 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 it has better light transmission characteristics than several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Because of that, it could be processed and formed without needing to be heated using sheet metal techniques, which include forming bends on a brake. For even 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 important, which can't be made from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and cannot be bent at room temperature.
Polycarbonate is often used in eye protection, along with other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require much greater impact-resistance. Many kinds of lenses are manufactured 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 crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
