Eat ChikenMakrolon Polycarbonate materials have a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a durable material. Whilst it has higher impact-resistance, it possesses lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection and polycarbonate exterior automobile equipment. The characteristics relating to polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), although 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 about 150 °C (302 °F), in order that it softens gradually 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) to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without cracking. Subsequently, it may be processed and formed at room temperature using standard sheet metal techniques, such as forming bends with 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 necessary, which should not be made from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and can’t be bent with out a heating process.
Polycarbonate is commonly found in eye protection, along with other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Several types 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 normally made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
