Polycarbonate plastic materials have a balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a sturdy material. Although it offers significant impact-resistance, it's got minimal scratch-resistance and thus a hard coating is often applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive equipment. The properties relating to polycarbonate tend to be along the lines of those of Acrylic PMMA materials, yet , polycarbonate is 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 gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. For that reason, for small changes in shape, it can be processed and formed without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which can not be crafted from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and cannot be bent with out a heating process.
Polycarbonate is frequently utilized in eye protection, along with other projectile-resistant see through applications that would normally indicate the use of glass, but require much greater impact-resistance. Many kinds of lenses are made of 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 normally made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
