Bayer Makrolon Polycarbonate materials offer a great blend of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a durable material. Although it features high impact-resistance, it possesses lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses and polycarbonate exterior vehicle equipment. The properties relating to polycarbonate are similar to that of those of Acrylic PMMA materials, and yet polycarbonate is undoubtedly 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking. Therefore, it is sometimes processed and formed without needing to be heated using sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually 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. Keep in mind that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is commonly utilized in eye protection, along with other projectile-resistant see through applications that would normally indicate the use of glass, but require 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
