Lexan Polycarbonate Sheets offer high impact strength

Bayer Makrolon Polycarbonate products give you a great blend of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Even though it features increased impact-resistance, it has lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior automobile equipment. The properties of polycarbonate tend to be like those of common Acrylic materials, yet , polycarbonate is undoubtedly 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 different types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens gradually 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 make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. For that reason, it is sometimes processed and formed   at room temperature using standard sheet metal techniques, for example forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are important, which can not be crafted from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and cannot be bent without heating.
Polycarbonate is commonly found in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require higher impact-resistance. Many kinds 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 made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
