Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable
Polycarbonate plastic materials offer a balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a high quality material. Although it has greater impact-resistance, it possesses minimal scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate tend to be similar those of Acrylic PMMA materials, and yet 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 most grades 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 must be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. As a result, it could be processed and formed without needing to be heated using sheet metal techniques, for example forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be made from sheet metal. Keep in mind that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent unless it is heated.
Polycarbonate is frequently found in eye protection, and also in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require higher impact-resistance. Many kinds of lenses are made of 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 normally manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
