Polycarbonate plastic products have a balance of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a durable material. Though it offers significant impact-resistance, it has low scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior motor vehicle components. The properties of polycarbonate are similar to those of common Acrylic materials, yet , polycarbonate is undoubtedly 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 kinds of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo large changes in basic shape without breaking or cracking. Subsequently, it could be processed and formed at room temperature using standard sheet metal techniques, which include forming bends on 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 essential, which cannot be made from sheet metal. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent without heating.
Polycarbonate is frequently found in eye protection, and also in other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Several types of lenses are manufactured 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 typically fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
