Makrolon Polycarbonate materials have a unique balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a durable material. Even though it offers greater impact-resistance, it has low scratch-resistance and thus a hard coating could be applied to polycarbonate eye protection and polycarbonate exterior auto components. The properties associated with polycarbonate tend to be like those of common Acrylic materials, but 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without breaking. As a result, it is sometimes processed and formed  at room temperature using standard sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are important, which can't be crafted from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and cannot be bent without heating.
Polycarbonate is commonly utilized in eye protection, and also in other projectile-resistant see through or lighting applications that would normally require the use of glass, but require 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
