Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance
Polycarbonate products offer a balance of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Whilst it features higher impact-resistance, it has minimal scratch-resistance and thus a hard coating may be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior auto components. The characteristics of polycarbonate tend to be similar to those of common Acrylic materials, and yet polycarbonate is going to be 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 kinds of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Therefore, it can 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 useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be produced from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it's brittle and can't be bent unless it is heated.
Polycarbonate is frequently found in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally require the use of glass, but require greater impact-resistance. Many kinds 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 normally made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
