Bayer Makrolon Polycarbonate materials offer a great blend of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a sturdy material. Although it offers higher 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 components. The characteristics of polycarbonate tend to be similar those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate is going to be 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 approximately 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking or breaking. Hence, it may be processed and formed at room temperature using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are essential, which may not be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require greater 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
