Sheffield Plastics Polycarbonate Flat Sheet are clear and tough

Makrolon Polycarbonate materials give you a great blend of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Although it offers increased impact-resistance, it has lower scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile equipment. The characteristics relating to polycarbonate are like those of Acrylic PMMA 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 has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. Hence, it is sometimes processed and formed   cold using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which can't be produced from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and cannot be bent without heating.
Polycarbonate is commonly 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 greater impact-resistance. Many kinds 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 typically made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
