Bayer Makrolon Polycarbonate materials have a great blend of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very rugged material. Whilst it features tremendous impact-resistance, it's got low scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive equipment. The characteristics relating to polycarbonate are like those of Acrylic PMMA materials, but 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 several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), as a result it softens gradually 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 stress-free products.
Unlike many thermoplastics, polycarbonate can undergo massive deformations without cracking. As a result, it could be processed and formed without needing to be heated using standard sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can't be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and can't be bent with out a heating process.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require greater impact-resistance. Several types of lenses are produced 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
