Polycarbonate materials offer a unique balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Even though it offers high impact-resistance, it has got reduced scratch-resistance and so a hard coating could be applied to polycarbonate eye wear lenses as well as polycarbonate exterior motor vehicle components. The characteristics associated with polycarbonate are comparable to those of common Acrylic 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 has a glass transition temperature of approximately 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. Because of this, it can be processed and formed at room temperature using standard sheet metal techniques, which include forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, as opposed to glass, has led to development of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several LCD screens, though CRT, plasma screen and other LCD technologies which still do require glass for its higher melting temperature and the ability to be etched with finer detail.
Other miscellaneous items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby goods are manufactured from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment could be needed. This either can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they begin to melt. The melted liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product , all in just a minute or so.

Bayer Makrolon Polycarbonate materials offer a balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very high quality material. Even though it offers high impact-resistance, it possesses minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye protection and polycarbonate exterior automotive components. The characteristics relating to polycarbonate tend to be similar to those of common Acrylic materials, but 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 several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Therefore, it is sometimes processed and formed cold using sheet metal techniques, for example forming bends on 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 necessary, which can't be produced from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is often used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require much greater impact-resistance. Several types of lenses are produced from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
