Covestro Makrolon Polycarbonate Sheet offer high impact strength
Polycarbonate products give you a unique balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a rugged material. Even though it features considerable impact-resistance, it's got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior motor vehicle equipment. The properties of polycarbonate tend to be along the lines of those of Acrylic PMMA materials, but 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 has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without cracking. For this reason, for small changes in shape, it can be processed and formed cold using 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 required, which may not be made from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is often used in eye protection, and also in other projectile-resistant optical type applications that would normally require the use of glass, but require much higher impact-resistance. Many different types 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 commonly made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
