Lexan Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate products offer a great blend of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very high quality material. Although it has extraordinary impact-resistance, it's got a lower scratch-resistance and so a hard coating is applied to polycarbonate eye protection and polycarbonate exterior motor vehicle equipment. The characteristics associated with polycarbonate tend to be along the lines of those of common Acrylic materials, yet , polycarbonate is 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 approximately 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. For this reason, it may be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be made from sheet metal. Note that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is often found in eye protection, and also in other projectile-resistant optical type applications that would normally require the use of glass, but require greater impact-resistance. Many different types of lenses are made of 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 commonly made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
