Covestro Makrolon Polycarbonate Sheeting are considered unbreakable
Bayer Makrolon Polycarbonate products give you a great blend of helpful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very long-lasting material. Even though it has increased impact-resistance, it has minimal scratch-resistance and thus a hard coating could be applied to polycarbonate eye wear lenses as well as polycarbonate exterior automobile components. The characteristics relating to polycarbonate are like those of Acrylic PMMA materials, 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has 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 should be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. Due to this fact, it may be processed and formed cold using sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are important, which should not be made from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and can't be bent unless it is heated.
Polycarbonate is often found in eye protection, along with other projectile-resistant see through applications that would normally indicate the use of glass, but require greater impact-resistance. Several 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 made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
