Covestro Makrolon Polycarbonate Sheet are clear and tough

Bayer Makrolon Polycarbonate materials offer a unique balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a long-lasting material. Though it offers considerable impact-resistance, it has got minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear lenses as well as polycarbonate exterior vehicle equipment. The properties associated with polycarbonate tend to be like those of Acrylic PMMA materials, although 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature of about 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 warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. Due to this fact, it could be processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which can't be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and can't be bent without heating.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Many kinds of lenses are manufactured 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
