Polycarbonate products give you a great blend of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very tough material. Whilst it offers very high impact-resistance, it possesses lower scratch-resistance and so a hard coating typically is applied to polycarbonate eyewear lenses as well as polycarbonate exterior motor vehicle components. The properties relating to polycarbonate are generally similar to that of those of polymethyl methacrylate (PMMA, acrylic), and yet 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 many kinds of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Because of this, for small changes in shape, it can be processed and formed without needing to be heated using standard sheet metal techniques, for example forming bends with a brake. For even 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 may not be produced from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is frequently found in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
