Lexan Polycarbonate Flat Sheet are clear and tough
Polycarbonate plastic products give you a unique balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a tough material. Whilst it offers significant impact-resistance, it's got low scratch-resistance and so a hard coating can be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior automobile equipment. The properties of polycarbonate tend to be like those of Acrylic PMMA materials, except 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 carries a glass transition temperature of about 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. Subsequently, it may be processed and formed without needing to be heated using standard sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which can not be produced from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent without heating.
Polycarbonate is commonly used in eye protection, along with other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Several 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 commonly made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
