Makrolon Polycarbonate materials have a great blend of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very long-lasting material. Whilst it features high impact-resistance, it possesses minimal scratch-resistance and thus a hard coating is applied to polycarbonate eye protection lenses and polycarbonate exterior automobile components. The properties of polycarbonate are similar to that of those of Acrylic PMMA materials, except polycarbonate is actually 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 around 150 °C (302 °F), therefore 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 make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. Therefore, it is sometimes processed and formed cold using standard sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can't be produced from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is often utilized in eye protection, as well as in other projectile-resistant see through applications that would normally require the use of glass, but require much 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 glasses 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.
