Lexan Polycarbonate Flat Sheet offer high impact strength

Polycarbonate plastic products offer a balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it features extraordinary impact-resistance, it's got minimal scratch-resistance and so a hard coating is often applied to polycarbonate eyewear as well as polycarbonate exterior automobile equipment. The properties of polycarbonate tend to be similar to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is actually 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 most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without cracking. For this reason, for small changes in shape, it can be processed and formed   at room temperature using standard sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which should not be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently found in eye protection, in addition to other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Several types of lenses are manufactured 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 constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
