Makrolon Polycarbonate products have a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very rugged material. Though it has very high impact-resistance, it has minimal scratch-resistance and thus a hard coating is applied to polycarbonate eyeglasses lenses and polycarbonate exterior automotive equipment. The properties associated with polycarbonate tend to be along the lines of those of common Acrylic materials, 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 different types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to produce strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking or cracking. Due to this fact, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, for example 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 crucial, which may not be created from sheet metal. Note that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is often used in eye protection, in addition to other projectile-resistant viewing and lighting applications that would normally be thought of as requiring the use of glass, but require 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 typically manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
