Covestro Makrolon Polycarbonate Sheet are clear and tough

Makrolon Polycarbonate materials give you a unique balance of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very rugged material. Although it features higher impact-resistance, it possesses lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear as well as polycarbonate exterior motor vehicle equipment. The properties associated with polycarbonate are generally like those of polymethyl methacrylate (PMMA, acrylic), and yet polycarbonate is definitely 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), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. For that reason, it is sometimes processed and formed   at room temperature using sheet metal techniques, which include 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 required, which can not be crafted from sheet metal. Be aware that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but is brittle and cannot be bent with out a heating process.
Polycarbonate is often utilized in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally require the use of glass, but require much higher impact-resistance. Many different types of lenses are made of 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
