Bayer Makrolon Polycarbonate products have a unique balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very sturdy material. Whilst it offers significant impact-resistance, it possesses minimal scratch-resistance and thus a hard coating may be applied to polycarbonate eye wear lenses and polycarbonate exterior automotive components. The properties of polycarbonate tend to be like those of Acrylic PMMA materials, but 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large changes in basic shape without breaking or cracking. Due to this fact, it could be processed and formed at room temperature using standard sheet metal techniques, such as forming bends with 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. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently 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 greater impact-resistance. Many kinds of lenses are produced 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 fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
