Polycarbonate plastic materials have a great blend of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very sturdy material. Even though it has high impact-resistance, it's got reduced scratch-resistance and thus a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior vehicle equipment. The properties of polycarbonate are generally along the lines of those of common Acrylic materials, yet , polycarbonate is actually 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 many different types of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), therefore 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 make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking or breaking. Subsequently, it may be processed and formed at room temperature using sheet metal techniques, such as forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which can't be made from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently utilized in eye protection, in addition to other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require much greater impact-resistance. Many kinds of lenses are produced 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 out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
