Covestro Makrolon Polycarbonate Sheets offering light weight and break resistance
Bayer Makrolon Polycarbonate materials offer a great blend of useful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it offers very high impact-resistance, it's got a lower scratch-resistance and thus a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components. The properties relating to polycarbonate tend to be similar to that of those of Acrylic PMMA materials, yet , polycarbonate is 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 of around 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive shape changes without cracking. Hence, for small changes in shape, it can be processed and formed without needing to be heated using standard sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which may not be made from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and cannot be bent with out a heating process.
Polycarbonate is commonly found in eye protection, and also in other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require much higher 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
