Sheffield Plastics Polycarbonate Sheets are clear and tough

Bayer Makrolon Polycarbonate products give you a great blend of useful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a tough material. Although it offers very high impact-resistance, it possesses low scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior motor vehicle equipment. The characteristics of polycarbonate tend to be similar to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is always 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 several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without breaking. Due to this fact, it can be processed and formed   without needing to be heated using sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is frequently utilized in eye protection, and also in other projectile-resistant see through applications that would normally indicate the use of glass, but require greater impact-resistance. Many different types of lenses are manufactured 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 from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
