Lexan Polycarbonate Flat Sheet are clear and tough
Polycarbonate plastic materials offer a great blend of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a rugged material. Although it features very high impact-resistance, it has reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear and polycarbonate exterior automobile components. The properties relating to polycarbonate are generally comparable to those of Acrylic PMMA 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 several types of glass.
Polycarbonate has 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 ought to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. For this reason, for small changes in shape, it can be processed and formed at room temperature using standard sheet metal techniques, such as forming bends with 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 necessary, which may not be crafted from sheet metal. Be aware that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but is brittle and can't be bent without heating.
Polycarbonate is often used in eye protection, as well as in other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require much higher impact-resistance. Many kinds of lenses are manufactured 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 commonly crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
