Makrolon Polycarbonate products offer a unique balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a sturdy material. Though it offers greater impact-resistance, it has got lower scratch-resistance and thus a hard coating is often applied to polycarbonate eye protection as well as polycarbonate exterior auto equipment. The characteristics relating to polycarbonate tend to be like those of Acrylic PMMA materials, but 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 several types of glass.
Polycarbonate has 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 are required to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without breaking or cracking. As a result, it is sometimes processed and formed without needing to be heated using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which should not be made from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and can't be bent with out a heating process.
Polycarbonate is commonly found in eye protection, along with other projectile-resistant see through applications that would normally require the use of glass, but require greater impact-resistance. Several types 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 normally made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
