Makrolon Polycarbonate products offer a balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Although it has significant impact-resistance, it has reduced scratch-resistance and so a hard coating is applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), and yet 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 has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), therefore it softens slowly 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) to produce strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking or breaking. Subsequently, it could be processed and formed cold using sheet metal techniques, for instance forming bends with a brake. Even for 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 essential, which can't be produced from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and cannot be bent at room temperature.
Polycarbonate is commonly utilized in eye protection, along with other projectile-resistant viewing and lighting applications that would normally require 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
