Lexan Polycarbonate Sheeting are clear and tough
Makrolon Polycarbonate materials have a great blend 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 tough material. Even though it has outstanding impact-resistance, it has a lower scratch-resistance and so a hard coating typically is applied to polycarbonate eye protection and polycarbonate exterior motor vehicle equipment. The properties associated with polycarbonate are comparable to those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate definitely 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. As a result, it may be processed and formed cold using standard sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which may not be created from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it's brittle and can't be bent without heating.
Polycarbonate is often used in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Several types of lenses are made of 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 made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
