Lexan Polycarbonate Sheet offer high impact strength
Polycarbonate materials give you a great blend of useful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a long-lasting material. Though it has outstanding impact-resistance, it has got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eyewear as well as polycarbonate exterior vehicle equipment. The properties associated with polycarbonate are along the lines of those of Acrylic PMMA materials, although 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 has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), as a result 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) to make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. Because of that, it is sometimes processed and formed without needing to be heated using standard sheet metal techniques, for instance forming bends with 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 may not be created from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant optical type applications that would normally require the use of glass, but require higher 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
