Bayer Makrolon Polycarbonate products offer a balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Even though it has exceptional impact-resistance, it has got a lower scratch-resistance and so a hard coating typically is applied to polycarbonate eyeglasses as well as polycarbonate exterior automobile equipment. The characteristics relating to polycarbonate are generally similar to that of those of Acrylic PMMA materials, and yet 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 it 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 ought to be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking or cracking. For that reason, for small changes in shape, it can be processed and formed at room temperature using sheet metal techniques, which include forming bends with a brake. For even 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 crucial, which should not be created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is often utilized in eye protection, in addition to other projectile-resistant optical type applications that would normally require the use of glass, but require much higher impact-resistance. Many different types of lenses are created from 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 normally made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
