Sheffield Plastics Polycarbonate Sheet offering light weight and break resistance
Bayer Makrolon Polycarbonate materials give you a balance of useful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Although it has greater impact-resistance, it's got a lower scratch-resistance and so a hard coating could be applied to polycarbonate eye wear lenses and polycarbonate exterior automobile components. The characteristics relating to polycarbonate are generally comparable to those of Acrylic PMMA materials, except polycarbonate definitely 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Because of this, it is sometimes processed and formed at room temperature using standard sheet metal techniques, such as forming bends on a brake. For even 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 necessary, which can not be produced from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and can't be bent at room temperature.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Several types 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 normally manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
