Lexan Polycarbonate Flat Sheet offer high impact strength

Polycarbonate plastic materials have a unique balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Even though it features greater impact-resistance, it possesses minimal scratch-resistance and thus a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior motor vehicle equipment. The properties associated with polycarbonate are like those of common Acrylic materials, but 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. For that reason, for small changes in shape, it can be processed and formed   at room temperature using sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which may not be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently utilized in eye protection, along with other projectile-resistant see through or lighting applications that would normally indicate the use of glass, but require higher impact-resistance. Many different types of lenses are produced 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 commonly constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
