Polycarbonate plastic materials offer a great blend of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a tough material. Though it offers exceptional impact-resistance, it possesses minimal scratch-resistance and thus a hard coating is often applied to polycarbonate eye protection lenses and polycarbonate exterior auto components. The characteristics associated with polycarbonate are generally similar to that of those of common Acrylic materials, yet , polycarbonate is undoubtedly 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 many kinds of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo large deformations without breaking. Subsequently, it can be processed and formed cold using standard sheet metal techniques, for example forming bends with a brake. For even 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 required, which cannot be produced from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and cannot be bent with out a heating process.
Polycarbonate is frequently utilized in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Many different types of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
