Bayer Makrolon Polycarbonate materials have a unique balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a long-lasting material. Although it has high impact-resistance, it possesses low scratch-resistance and so a hard coating can be applied to polycarbonate eyewear lenses as well as polycarbonate exterior motor vehicle components. The characteristics of polycarbonate are similar to those of common Acrylic materials, but polycarbonate definitely 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 most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), in order that 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) to help make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking or cracking. For this reason, it could be processed and formed at room temperature using sheet metal techniques, which include forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which cannot be produced from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and cannot be bent without heating.
Polycarbonate is often used in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require greater impact-resistance. Several types 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
