Makrolon Polycarbonate products give you a great blend of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very long-lasting material. Though it has increased impact-resistance, it has got reduced scratch-resistance and so a hard coating could be applied to polycarbonate eyewear and polycarbonate exterior motor vehicle components. The properties of polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), except 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large changes in basic shape without cracking or breaking. Subsequently, it could be processed and formed without needing to be heated using sheet metal techniques, for example forming bends with a brake. For even 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 important, which can't be made from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and can't be bent at room temperature.
Polycarbonate is frequently used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require higher 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 normally crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
