Makrolon Polycarbonate materials give you a great blend of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a durable material. Though it features exceptional impact-resistance, it has got a lower scratch-resistance and thus a hard coating is often applied to polycarbonate eyeglasses as well as polycarbonate exterior automotive equipment. The properties of polycarbonate are comparable to those of polymethyl methacrylate (PMMA, acrylic), yet , 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 kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher 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 shape changes without cracking or breaking. Because of that, it could be processed and formed at room temperature using sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which should not be produced from sheet metal. Note that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it is brittle and can't be bent without heating.
Polycarbonate is frequently used in eye protection, in addition to other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require greater impact-resistance. Many kinds of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
