Lexan Polycarbonate Flat Sheet are considered unbreakable
Polycarbonate products give you a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a rugged material. Although it offers high impact-resistance, it's got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior auto equipment. The properties relating to polycarbonate are comparable to those of Acrylic PMMA materials, although polycarbonate is always 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 of approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. As a result, it could be processed and formed at room temperature using sheet metal techniques, such as forming bends on a brake. Even for 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 necessary, which can't be made from sheet metal. Be aware that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is commonly found in eye protection, in addition to other projectile-resistant viewing and lighting applications that would normally indicate 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
