Covestro Makrolon Polycarbonate Flat Sheet offer high impact strength

Bayer Makrolon Polycarbonate products have a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a high quality material. Whilst it offers outstanding impact-resistance, it has got lower scratch-resistance and thus a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automobile equipment. The properties relating to polycarbonate tend to be similar to those of Acrylic PMMA materials, although polycarbonate is actually 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 kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking or breaking. For that reason, it is sometimes processed and formed   at room temperature using standard sheet metal techniques, for example forming bends with a brake. For even sharp angle bends having 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 cannot be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.
Polycarbonate is often used in eye protection, along with other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require greater 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
