Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength
Polycarbonate products have a unique balance of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Although it features high impact-resistance, it possesses reduced scratch-resistance and so a hard coating is often applied to polycarbonate eye wear and polycarbonate exterior motor vehicle components. The characteristics of polycarbonate are along the lines of those of common Acrylic materials, although 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 approximately 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large changes in basic shape without breaking or cracking. Hence, for small changes in shape, it can be processed and formed cold using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which should not be made from sheet metal. Remember that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent with out a heating process.
Polycarbonate is commonly found in eye protection, along with other projectile-resistant optical type applications that would normally require the use of glass, but require much higher impact-resistance. Many different types of lenses are created 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 normally produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
