Bayer Makrolon Polycarbonate Sheets are considered unbreakable
Bayer Makrolon Polycarbonate products offer a great blend of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Whilst it has very high impact-resistance, it possesses a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection lenses and polycarbonate exterior automobile components. The properties of polycarbonate are generally similar 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 has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without cracking. For that reason, for small changes in shape, it can be processed and formed without needing to be heated using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which should not be produced from sheet metal. Be aware that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it is brittle and can't be bent without heating.
Polycarbonate is frequently used in eye protection, as well as in other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Many kinds 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 made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
