Sheffield Plastics Polycarbonate Sheeting offer high impact strength
Polycarbonate plastic materials give you a great blend of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is a very durable material. Even though it features outstanding impact-resistance, it possesses reduced scratch-resistance and thus a hard coating may be applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile components. The properties relating to polycarbonate are generally similar to that of those of common Acrylic materials, but polycarbonate is always 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 slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking. For this reason, it could be processed and formed at room temperature using sheet metal techniques, for example forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are important, which should not be crafted from sheet metal. Remember that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it is brittle and can't be bent at room temperature.
Polycarbonate is often found 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 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 normally crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
