Lexan Polycarbonate Sheet are considered unbreakable
Polycarbonate plastic materials give you a balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very high quality material. Whilst it features exceptional impact-resistance, it's got reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye protection as well as polycarbonate exterior auto equipment. The characteristics relating to polycarbonate are generally like those of common Acrylic materials, but polycarbonate is definitely 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), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. Subsequently, it may be processed and formed cold using standard sheet metal techniques, for example forming bends with a brake. Even for 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 needed, which can't be produced from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it's brittle and cannot be bent unless it is heated.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
