Makrolon Polycarbonate products offer a great blend of helpful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very high quality material. Whilst it features very high impact-resistance, it has low scratch-resistance and thus a hard coating typically is applied to polycarbonate eyewear lenses as well as polycarbonate exterior motor vehicle components. The characteristics of polycarbonate are generally comparable to those of Acrylic PMMA materials, yet , 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 near 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic shape changes without cracking. Hence, it can be processed and formed  cold using standard sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are required, which should not be made from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and can't be bent without heating.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally indicate 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
