Polycarbonate plastic products give you a great blend of useful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it features exceptional impact-resistance, it has low scratch-resistance and so a hard coating typically is applied to polycarbonate eyewear and polycarbonate exterior auto equipment. The characteristics relating to polycarbonate are similar to that of those of Acrylic PMMA 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 carries a glass transition temperature near 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 make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo massive shape changes without cracking or breaking. As a result, it is sometimes processed and formed at room temperature using sheet metal techniques, such as 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 required, which can not be crafted from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant optical type applications that would normally require the use of glass, but require much greater impact-resistance. Several 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
