Makrolon Polycarbonate products have a balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a rugged material. Even though it offers exceptional impact-resistance, it possesses lower scratch-resistance and thus a hard coating is applied to polycarbonate eye wear lenses as well as polycarbonate exterior auto equipment. The properties relating to polycarbonate are similar to that of those of common Acrylic materials, and 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually 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 almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Hence, it is sometimes processed and formed cold using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be made from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is frequently found in eye protection, and also in other projectile-resistant see through or lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Several types of lenses are manufactured 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 typically made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
